Debian DSA-3539-1 : srtp - security update

high Nessus Plugin ID 90322
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
