Debian DLA-393-1 : srtp security update

high Nessus Plugin ID 87977
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 update.

Description

Prevent potential DoS attack due to lack of bounds checking on RTP header CSRC count and extension header length. Credit goes to Randell Jesup and the Firefox team for reporting this issue.

(As there is no aead mode available in the Squeeze version, only srtp_unprotect() needed to be patched)

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
