Debian DSA-3539-1 : srtp - security update

high Nessus Plugin ID 90322

Synopsis

The remote Debian host is missing a security-related update.

Description

Randell Jesup and the Firefox team discovered that srtp, Cisco's reference implementation of the Secure Real-time Transport Protocol (SRTP), does not properly handle RTP header CSRC count and extension header length. A remote attacker can exploit this vulnerability to crash an application linked against libsrtp, resulting in a denial of service.

Solution

Upgrade the srtp packages.

For the oldstable distribution (wheezy), this problem has been fixed in version 1.4.4+20100615~dfsg-2+deb7u2.

For the stable distribution (jessie), this problem has been fixed in version 1.4.5~20130609~dfsg-1.1+deb8u1.
