Debian DLA-1003-1 : unrar-nonfree security update

critical Nessus Plugin ID 101065

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was reported that unrar fixed a VMSF_DELTA memory corruption issue in their latest version unrarsrc-5.5.5.tar.gz. This problem was reported to Sophos AV in 2012 but never reach upstream rar.

For Debian 7 'Wheezy', these problems have been fixed in version 1:4.1.4-1+deb7u2.

We recommend that you upgrade your unrar-nonfree packages.

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 unrar package.
