Debian DLA-1014-1 : libclamunrar security update

high Nessus Plugin ID 101239


The remote Debian host is missing a security update.


It was discovered that there was an arbitrary code execution vulnerability in libcamunrar, a library to add unrar support to the Clam anti-virus software.

This was caused by an integer overflow resulting in a negative value of the ``DestPos`` variable, which allows the attacker to write out of bounds when setting ``Mem[DestPos]``.

For Debian 7 'Wheezy', this issue has been fixed in libclamunrar version 0.99-0+deb7u2.

We recommend that you upgrade your libclamunrar 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.


Upgrade the affected libclamunrar7 package.
