Homebrew vulnerability analysis and mitigation
Overview
Deark v.1.6.2 contains a stack overflow vulnerability in the doprismread_palette() function located in /modules/atari-img.c. The vulnerability was discovered and reported on September 18, 2022 (GitHub Issue).
Technical details
The vulnerability is a stack-buffer-overflow that occurs in the doprismread_palette function at line 331 of modules/atari-img.c. When processing certain malformed input files, the function attempts to read 4 bytes beyond the bounds of an allocated buffer named 'pal1' on the stack. This was confirmed through AddressSanitizer analysis which showed the overflow occurring at offset 1056 of a buffer allocated with size [32, 1056) (GitHub Issue).
Impact
The vulnerability could lead to a denial of service condition through application crash. Given that it's a stack buffer overflow, there may also be potential for arbitrary code execution, though this has not been explicitly confirmed (GitHub Issue).
Mitigation and workarounds
Users should upgrade to a version newer than v1.6.2. The vulnerability was reported to the project maintainers through GitHub's issue tracking system (GitHub Issue).
