Debian DSA-2995-1 : lzo2 - security update

high Nessus Plugin ID 76976

Synopsis

The remote Debian host is missing a security-related update.

Description

Don A. Bailey from Lab Mouse Security discovered an integer overflow flaw in the way the lzo library decompressed certain archives compressed with the LZO algorithm. An attacker could create a specially crafted LZO-compressed input that, when decompressed by an application using the lzo library, would cause that application to crash or, potentially, execute arbitrary code.

Solution

Upgrade the lzo2 packages.

For the stable distribution (wheezy), this problem has been fixed in version 2.06-1+deb7u1.
