CyberRota Analysis
AI-GeneratedThe PJSIP multimedia communication library is vulnerable due to an out-of-bounds write in the AVI parser, which can be exploited by crafted AVI files to cause memory corruption. This vulnerability can lead to application crashes during local playback and poses a greater risk for applications that process untrusted AVI sources. Organizations utilizing PJSIP for multimedia applications should prioritize addressing this issue, especially if they handle untrusted inputs.

Original NVD Description
PJSIP is a free and open source multimedia communication library written in C. In 2.17 and earlier, the PJSIP AVI parser in pjmedia/src/pjmedia/avi_player.c uses an input-file video chunk length as the number of bytes copied into a frame buffer whose capacity is derived from the declared media dimensions. A crafted AVI file can therefore cause an attacker-controlled out-of-bounds write past the heap allocation when an application plays the file or pulls its frames. The existing size assertion does not protect production release builds, where assertions are disabled. Typical local playback can crash the process, while applications that accept untrusted AVI sources expose a stronger memory-corruption condition. No fixed version is available as of this review.
