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.

For the stable distribution (wheezy), this problem has been fixed in version 2.06-1+deb7u1. For the testing distribution (jessie), this problem has been fixed in version 2.08-1. For the unstable distribution (sid), this problem has been fixed in version 2.08-1. We recommend that you upgrade your lzo2 packages.
