CWE-121
AllowedStack-based Buffer Overflow
Abstraction: Variant · Status: Draft
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
5831 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2025-07-30 21:31 – Updated: 2025-07-30 21:31A buffer overflow vulnerability exists in the upload.cgi module of the iptime NAS firmware v1.5.04. The vulnerability arises due to the unsafe use of the strcpy function to copy attacker-controlled data from the CONTENT_TYPE HTTP header into a fixed-size stack buffer (v8, allocated 8 bytes) without bounds checking. Since this operation occurs before authentication logic is executed, the vulnerability is exploitable pre-authentication.

Vulnerability from github – Published: 2026-10-08 03:31 – Updated: 2026-10-08 03:31A stack-based buffer overflow vulnerability exists in the security library component of Brocade Fabric OS versions before 10.0.1. When parsing uploaded X.509 PEM certificates for management display, the system improperly validates the length of the Authority Key Identifier (AKI) extension before copying string tokens into an internal memory buffer. An authenticated user with administrative privileges to import custom certificates can supply a certificate containing an intentionally oversized AKI extension. When the system processes or renders the certificate attributes, this can trigger a stack memory corruption leading to a denial-of-service (DoS) condition by crashing the management daemon.

jfs: xattr: fix buffer overflow for invalid xattr
When an xattr size is not what is expected, it is printed out to the kernel log in hex format as a form of debugging. But when that xattr size is bigger than the expected size, printing it out can cause an access off the end of the buffer.
Fix this all up by properly restricting the size of the debug hex dump in the kernel log.

Mitigation MIT-10
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
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Implement and perform bounds checking on input.
Mitigation
Do not use dangerous functions such as gets. Use safer, equivalent functions which check for boundary errors.
Mitigation MIT-11
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].
