CWE-823
AllowedUse of Out-of-range Pointer Offset
Abstraction: Base · Status: Incomplete
The product performs pointer arithmetic on a valid pointer, but it uses an offset that can point outside of the intended range of valid memory locations for the resulting pointer.

GHSA-X6H9-CX79-JJJV
Vulnerability from github – Published: 2024-03-18 12:30 – Updated: 2024-03-18 12:30An out-of-bounds stack write flaw was found in unixODBC on 64-bit architectures where the caller has 4 bytes and callee writes 8 bytes. This issue may go unnoticed on little-endian architectures, while big-endian architectures can be broken.

CAPEC-129: Pointer Manipulation
This attack pattern involves an adversary manipulating a pointer within a target application resulting in the application accessing an unintended memory location. This can result in the crashing of the application or, for certain pointer values, access to data that would not normally be possible or the execution of arbitrary code. Since pointers are simply integer variables, Integer Attacks may often be used in Pointer Attacks.
