Description Yury German Gentoo Infrastructure gentoo-dev 2014-06-27 01:02:17 UTC
It is suspected that this package is vulnerable to a security vulnerability in LZO. As such we ask maintainers with packages suspected to be vulnerable to verify if the package is (or have been) affected. 

Please see the information contained in the tracker bug 515246. "An integer overflow may occur when processing any variant of a "literal run" in the lzo1x_decompress_safe function. Each of these three locations is subject to an integer overflow when processing zero bytes.", additional information about the upstream vulnerability is available at http://seclists.org/oss-sec/2014/q2/665
