CyberRota Analysis
AI-GeneratedFFmpeg versions up to 8.1.2 are vulnerable due to a heap out-of-bounds write in the PNG and APNG encoders, which can be exploited by remote attackers through specially crafted PNG images containing malicious eXIf chunks. This vulnerability can lead to heap memory corruption, process crashes, and potentially arbitrary code execution. Organizations using affected versions of FFmpeg should prioritize patching to mitigate the risk of exploitation.

Original NVD Description
FFmpeg through 8.1.2, fixed in commit b506faf, contains a heap out-of-bounds write vulnerability in the native PNG and APNG encoders that allows remote attackers to corrupt heap memory by supplying a crafted PNG image with a malicious eXIf chunk. Attackers can craft an eXIf chunk where multiple IFD entries reference the same large value payload, causing canonical serialization to expand the output far beyond the undersized allocation estimated by add_exif_profile_size(), resulting in png_write_chunk() writing tens of thousands of bytes past the buffer boundary, leading to deterministic heap corruption, process crash, and potentially arbitrary code execution.
