Summary
Wasmtime: Miscompiled guest heap access enables sandbox escape on aarch64 Cranelift
Details

Impact

Wasmtime's Cranelift compilation backend contains a bug on aarch64 when performing a certain shape of heap accesses which means that the wrong address is accessed. When combined with explicit bounds checks a guest WebAssembly module this can create a situation where there are two diverging computations for the same address: one for the address to bounds-check and one for the address to load. This difference in address being operated on means that a guest module can pass a bounds check but then load a different address. Combined together this enables an arbitrary read/write primitive for guest WebAssembly when accesssing host memory. This is a sandbox escape as guests are able to read/write arbitrary host memory.

This vulnerability has a few ingredients, all of which must be met, for this situation to occur and bypass the sandbox restrictions:

  • This miscompiled shape of load only occurs on 64-bit WebAssembly linear memories, or when Config::wasm_memory64 is enabled. 32-bit WebAssembly is not affected.
  • Spectre mitigations or signals-based-traps must be disabled. When spectre mitigations are enabled then the offending shape of load is not generated. When signals-based-traps are disabled then spectre mitigations are also automatically disabled.

The specific bug in Cranelift is a miscompile of a load of the shape load(iadd(base, ishl(index, amt))) where amt is a constant. The amt value is masked incorrectly to test if it's a certain value, and this incorrect mask means that Cranelift can pattern-match this lowering rule during instruction selection erroneously, diverging from WebAssembly's and Cranelift's semantics. This incorrect lowering would, for example, load an address much further away than intended as the correct address's computation would have wrapped around to a smaller value insetad.

Patches

Wasmtime 36.0.7, 42.0.2, and 43.0.1 have been issued to fix this bug. Users are recommended to update to these patched versions of Wasmtime.

Workarounds

This bug only affects users of Cranelift on aarch64. Cranelift on other platforms is not affected. Additionally this only affects 64-bit WebAssembly linear memories, so if Config::wasm_memory64 is disabled then hosts are not affected. Note that Config::wasm_memory64 is enabled by default. If spectre mitigations are enabled, which are enabled by default, then hosts are not affected by this issue.

Summary
ImageSharp: CCITT fax decompression (T4/Modified Huffman): unbounded WriteBits overflows strip buffer — heap OOB write in SixLabors.ImageSharp
Details

Summary

When decoding a fax-compressed strip TIFF (Compression=3 / Group 3 1D, or Compression=2 / Modified Huffman), the CCITT decompressors write decoded runs through BitWriterUtils.WriteBits/WriteBit/WriteZeroBit, which advance and write bits via Unsafe.Add with read-modify-write semantics — without ever comparing the write position against the target buffer length. The strip buffer is sized ImageWidth × RowsPerStrip (8 bytes in the PoC), but two independent defects let an attacker write tens of millions of bits past it: (a) T4 only increments rowsWritten when an EOL code is read, and one ReadNextRun accumulates unlimited makeup codes (+2560 px per 12-bit code) into a single RunLength that WritePixelRun then writes in one shot; (b) Modified Huffman writes before validating (pixelsWritten > Width is checked at :90-93, after the write at :56-63), so the overflow completes even though an exception is thrown later. One crafted ~90 KB file writes ~19.2 MB linearly past an 8-byte buffer and deterministically kills the process; the write offset and length are fully attacker-controlled (classic heap-corruption primitive on the managed heap).

Verified at commit 5cd4d0d26a82a9549f297a237aea9cf665bddff8 (main; latest release v4.1.0, the supported major). A related tiled-path variant (tile-buffer width mismatch) was reported separately as GHSA-v76p-62qx-wwq2 — this report covers the distinct strip-path root cause.

Details

Root cause: the bit-writing sink has no bounds check, and neither decompressor constrains run lengths against the strip buffer.

Attack surface: Image.Load(stream) on an attacker-supplied strip TIFF (TiffDecoderCore.DecodeStripsChunky → TiffDecompressorsFactory.Create → Decompress). Default configuration, no authentication, no user interaction — a plain strip TIFF (far more common than the tiled variant) with Compression=2 or 3 and a chain of CCITT makeup codes.

Relationship to GHSA-v76p-62qx-wwq2: that report is the tiled variant — a caller-side width mismatch (TiffDecompressorsFactory drops tile parameters) that overflows with perfectly legal run codes. This report is the strip variant — the callee-side missing bounds check plus T4's EOL-only row accounting and MH's write-before-validate. Fixing the caller mismatch does not address this vector; bounding BitWriterUtils addresses both (see remediation).

Suggested remediation: 1. Bound BitWriterUtils.WriteBits/WriteBit/WriteZeroBit against buffer.Length*8 (return bool / throw ImageFormatException) — do not rely on caller discipline. 2. In the T4/MH decompress loops, validate (bitsWritten + RunLength) <= buffer.Length*8 before writing; abort T4 when accumulated rows exceed stripHeight instead of waiting for the loop to end naturally. 3. In Modified Huffman, move the pixelsWritten > Width check before the actual write. 4. Regression fuzz cases: Compression=2/3, EOL-less oversized makeup chains, edge widths; strip and tiled paths share the same constraint.

PoC

Full PoC posted as the first comment below: Program.cs (driver), poc-tiff-t4.tif + poc-tiff-mh.tif (crafted files, ~90 KB each, base64 inline), README.

  1. Build a console project referencing src/ImageSharp/ImageSharp.csproj, run it against either crafted file (or call Image.Load on it).
  2. PoC layout: TIFF (II, 42), ImageWidth=64, ImageLength=1, BitsPerSample=1, Photometric=WhiteIsZero, RowsPerStrip=1; strip data = EOL(12bit) + 60000× white makeup 2560 (000000011111) + white terminating code (000111) — declared run ≈ 153,600,001 px ≈ 19.2 MB into an 8-byte buffer.
  3. Observed (both variants):

strip payload 90003 bytes, claimed run ~153,600,001 px = 19,200,000 bytes into 8-byte buffer Fatal error. System.AccessViolationException: Attempted to read or write protected memory. at SixLabors.ImageSharp.Formats.Tiff.Compression.BitWriterUtils.WriteBits(Span`1<Byte>, IntPtr, IntPtr, Byte) at ...ModifiedHuffmanTiffCompression.Decompress(...) at SixLabors.ImageSharp.Formats.Tiff.TiffDecoderCore.DecodeStripsChunky[Rgba32](...) Aborted (core dumped); exit=134

The T4 variant crashes identically at T4TiffCompression.WritePixelRun → BitWriterUtils.WriteBits. 4. Control: an equivalent file without the makeup chain (legal EOL-delimited rows) decodes normally — the crash comes from the oversized runs, not the container.

Impact

  • What it is: out-of-bounds write (CWE-787). For any service decoding untrusted TIFFs (image hosting/transcoding/thumbnails/CMS): reliable remote DoS (uncatchable fatal process crash), plus a heap OOB write with attacker-controlled offset and length — a realistic heap-corruption / potential code-execution surface. In scope of your SECURITY.md as a library vulnerability.
  • Who is impacted: applications decoding untrusted TIFF with SixLabors.ImageSharp at the current major (verified on main past v4.1.0); plain strip TIFFs with Compression=2/3 are the trigger, which ordinary TIFF writers can produce.

Default configuration, no authentication, no user interaction \u2014 a plain strip TIFF (far more common than the tiled variant) with Compression=2 or 3 and a chain of CCITT makeup codes.\n\nRelationship to GHSA-v76p-62qx-wwq2: that report is the **tiled** variant \u2014 a caller-side width mismatch (`TiffDecompressorsFactory` drops tile parameters) that overflows with perfectly legal run codes. This report is the **strip** variant \u2014 the callee-side missing bounds check plus T4\u0027s EOL-only row accounting and MH\u0027s write-before-validate. Fixing the caller mismatch does not address this vector; bounding `BitWriterUtils` addresses both (see remediation).\n\n**Suggested remediation:**\n1. Bound `BitWriterUtils.WriteBits/WriteBit/WriteZeroBit` against `buffer.Length*8` (return bool / throw `ImageFormatException`) \u2014 do not rely on caller discipline.\n2. In the T4/MH decompress loops, validate `(bitsWritten + RunLength) \u003c= buffer.Length*8` **before** writing; abort T4 when accumulated rows exceed stripHeight instead of waiting for the loop to end naturally.\n3. In Modified Huffman, move the `pixelsWritten \u003e Width` check before the actual write.\n4. Regression fuzz cases: Compression=2/3, EOL-less oversized makeup chains, edge widths; strip and tiled paths share the same constraint.\n\n## PoC\n\nFull PoC posted as the first comment below: `Program.cs` (driver), `poc-tiff-t4.tif` + `poc-tiff-mh.tif` (crafted files, ~90 KB each, base64 inline), README.\n\n1. Build a console project referencing `src/ImageSharp/ImageSharp.csproj`, run it against either crafted file (or call `Image.Load` on it).\n2. PoC layout: TIFF (II, 42), ImageWidth=64, ImageLength=1, BitsPerSample=1, Photometric=WhiteIsZero, RowsPerStrip=1; strip data = `EOL(12bit)` + 60000\u00d7 `white makeup 2560 (000000011111)` + `white terminating code (000111)` \u2014 declared run \u2248 153,600,001 px \u2248 19.2 MB into an 8-byte buffer.\n3. Observed (both variants):\n\n   ```\n   strip payload 90003 bytes, claimed run ~153,600,001 px = 19,200,000 bytes into 8-byte buffer\n   Fatal error. System.AccessViolationException: Attempted to read or write protected memory.\n      at SixLabors.ImageSharp.Formats.Tiff.Compression.BitWriterUtils.WriteBits(Span`1\u003cByte\u003e, IntPtr, IntPtr, Byte)\n      at ...ModifiedHuffmanTiffCompression.Decompress(...)\n      at SixLabors.ImageSharp.Formats.Tiff.TiffDecoderCore.DecodeStripsChunky[Rgba32](...)\n   Aborted (core dumped); exit=134\n   ```\n\n   The T4 variant crashes identically at `T4TiffCompression.WritePixelRun \u2192 BitWriterUtils.WriteBits`.\n4. Control: an equivalent file without the makeup chain (legal EOL-delimited rows) decodes normally \u2014 the crash comes from the oversized runs, not the container.\n\n## Impact\n\n- **What it is:** out-of-bounds write (CWE-787). For any service decoding untrusted TIFFs (image hosting/transcoding/thumbnails/CMS): reliable remote DoS (uncatchable fatal process crash), plus a heap OOB write with attacker-controlled offset and length \u2014 a realistic heap-corruption / potential code-execution surface. In scope of your SECURITY.md as a library vulnerability.\n- **Who is impacted:** applications decoding untrusted TIFF with SixLabors.ImageSharp at the current major (verified on main past v4.1.0); plain strip TIFFs with Compression=2/3 are the trigger, which ordinary TIFF writers can produce.\n\n---\n\n---\n\nReported by **Kimi Security Team** (bug-report@moonshot.ai).",

Mitigation MIT-3
Requirements

Strategy: Language Selection

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow protection, but the protection can be disabled by the programmer.
  • Be wary that a language's interface to native code may still be subject to overflows, even if the language itself is theoretically safe.
Mitigation MIT-4.1
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • Examples include the Safe C String Library (SafeStr) by Messier and Viega [REF-57], and the Strsafe.h library from Microsoft [REF-56]. These libraries provide safer versions of overflow-prone string-handling functions.
Mitigation MIT-10
Operation Build and Compilation

Strategy: Environment Hardening

  • Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking.
  • D3-SFCV (Stack Frame Canary Validation) from D3FEND [REF-1334] discusses canary-based detection in detail.
Mitigation MIT-9
Implementation
  • Consider adhering to the following rules when allocating and managing an application's memory:
  • Double check that the buffer is as large as specified.
  • When using functions that accept a number of bytes to copy, such as strncpy(), be aware that if the destination buffer size is equal to the source buffer size, it may not NULL-terminate the string.
  • Check buffer boundaries if accessing the buffer in a loop and make sure there is no danger of writing past the allocated space.
  • If necessary, truncate all input strings to a reasonable length before passing them to the copy and concatenation functions.
Mitigation MIT-11
Operation Build and Compilation

Strategy: Environment Hardening

  • Run or compile the software using features or extensions that randomly arrange the positions of a program's executable and libraries in memory. Because this makes the addresses unpredictable, it can prevent an attacker from reliably jumping to exploitable code.
  • Examples include Address Space Layout Randomization (ASLR) [REF-58] [REF-60] and Position-Independent Executables (PIE) [REF-64]. Imported modules may be similarly realigned if their default memory addresses conflict with other modules, in a process known as "rebasing" (for Windows) and "prelinking" (for Linux) [REF-1332] using randomly generated addresses. ASLR for libraries cannot be used in conjunction with prelink since it would require relocating the libraries at run-time, defeating the whole purpose of prelinking.
  • For more information on these techniques see D3-SAOR (Segment Address Offset Randomization) from D3FEND [REF-1335].
Mitigation MIT-12
Operation

Strategy: Environment Hardening

  • Use a CPU and operating system that offers Data Execution Protection (using hardware NX or XD bits) or the equivalent techniques that simulate this feature in software, such as PaX [REF-60] [REF-61]. These techniques ensure that any instruction executed is exclusively at a memory address that is part of the code segment.
  • For more information on these techniques see D3-PSEP (Process Segment Execution Prevention) from D3FEND [REF-1336].
Mitigation MIT-13
Implementation

Replace unbounded copy functions with analogous functions that support length arguments, such as strcpy with strncpy. Create these if they are not available.

No CAPEC attack patterns related to this CWE.
