Description Yury German Gentoo Infrastructure

2014-06-27 01:00:11 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

Reproducible: Didn't try

Remmina does not embed a copy of the LZO library in its source. The only problem I see when remmina[freerdp] pulls freerdp[ffmpeg] which then pulls a vulnerable version of ffmpeg or libav.

As previously stated, this issue does not reside directly in the source code. Which I have confirmed. Dependencies introduce this through the FFmpeg library which has been mitigated in bug 515282.  Libav issues have been mitigated in bug 515234.
