NixOS vulnerability analysis and mitigation
Overview
SWFTools commit 772e55a2 was discovered to contain a stack overflow vulnerability via ImageStream::getPixel(unsigned char*) at /xpdf/Stream.cc. The vulnerability was disclosed on September 23, 2022 (MITRE, NVD).
Technical details
The vulnerability exists in the ImageStream::getPixel function located in the /xpdf/Stream.cc file. When processing certain PDF files, the function can trigger a stack overflow condition. This occurs when handling image data through the pdf2swf conversion tool (GitHub Issue).
Impact
A successful exploitation of this vulnerability could allow an attacker to cause a denial of service (DoS) condition or potentially execute arbitrary code. The vulnerability requires local access and user interaction, as it is triggered when processing specially crafted PDF files (AttackerKB).
Mitigation and workarounds
Users should update to a newer version of SWFTools that contains patches for this vulnerability. If updating is not immediately possible, users should exercise caution when processing untrusted PDF files with the pdf2swf tool (MITRE).
