## Description

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 `pjmedia\_sdp\_print(),
pjmedia\_sdp\_media\_print()`. Applications that do not use PJSUA2 and do not
directly call `pjmedia\_sdp\_print()` or `pjmedia\_sdp\_media\_print()` should
not be affected. A patch is available on the `master` branch of the
`pjsip/pjproject` GitHub repository. There are currently no known
workarounds.
