medium Tenable Cloud Security Plugin ID 406414

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - PJSIP is a free and open source multimedia communication library written in C language implementing
 standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In PJSIP before version 2.11.1, there
 are a couple of issues found in the SSL socket. First, a race condition between callback and destroy, due
 to the accepted socket having no group lock. Second, the SSL socket parent/listener may get destroyed
 during handshake. Both issues were reported to happen intermittently in heavy load TLS connections. They
 cause a crash, resulting in a denial of service. These are fixed in version 2.11.1. (CVE-2021-32686)
