Debian DLA-393-1 : srtp security update

high Nessus Plugin ID 87977

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.
