Debian DLA-420-1 : libmatroska security update

high Nessus Plugin ID 88845

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a invalid memory address issue in libmatroska, an extensible open standard audio/video container format.

When reading a block group or a simple block that uses EBML lacing the frame sizes indicated in the lacing weren't checked against the available number of bytes. If the indicated frame size was bigger than the whole block's size the parser would read beyond the end of the buffer resulting in a heap information leak.

For Debian 6 Squeeze, this issue has been fixed in libmatroska version 0.8.1-1.1+deb6u1.

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 libmatroska-dev, and libmatroska0 packages.
