PJSIP is a free and open source multimedia communication library written in C language. In versions prior to and including 2.12 PJSIP there is a stack-buffer overflow vulnerability which only impacts PJSIP users who accept hashed digest credentials (credentials with datatype PJSIPCREDDATADIGEST). This issue has been patched in the master branch of the PJSIP repository and will be included with the next release. Users unable to upgrade need to check that the hashed digest data length must be equal to PJSIPMD5STRLEN before passing to PJSIP.

PJSIP is a free and open source multimedia communication library written in C. Versions 2.12 and prior contain a stack buffer overflow vulnerability that affects PJSUA2 users or users that call the API pjmediasdpprint(), pjmediasdpmediaprint(). Applications that do not use PJSUA2 and do not directly call pjmediasdpprint() or pjmediasdpmediaprint() should not be affected. A patch is available on the master branch of the pjsip/pjproject GitHub repository. There are currently no known workarounds.

PJSIP is a free and open source multimedia communication library written in C. A denial-of-service vulnerability affects applications on a 32-bit systems that use PJSIP versions 2.12 and prior to play/read invalid WAV files. The vulnerability occurs when reading WAV file data chunks with length greater than 31-bit integers. The vulnerability does not affect 64-bit apps and should not affect apps that only plays trusted WAV files. A patch is available on the master branch of the pjsip/project GitHub repository. As a workaround, apps can reject a WAV file received from an unknown source or validate the file first.
