| written in C language implementing standard based protocols such as
| SIP, SDP, RTP, STUN, TURN, and ICE. In versions prior to and including
| 2.12.1 a stack buffer overflow vulnerability affects PJSIP users that
| use STUN in their applications, either by: setting a STUN server in
| their account/media config in PJSUA/PJSUA2 level, or directly using
| `pjlib-util/stun_simple` API. A patch is available in commit 450baca
| which should be included in the next release. There are no known
| workarounds for this issue.
