Description Agostino Sarubbo gentoo-dev 2013-10-14 18:58:19 UTC
From ${URL} :


Some vulnerabilities have been reported in FFmpeg, which can be exploited by malicious people to 
cause a DoS (Denial of Service) and potentially compromise an application using the library.

1) Some errors within libavcodec/vmnc.c can be exploited to cause out of bounds read memory 

2) Some integer overflow errors within the "decode_frame()" function (libavcodec/vmnc.c) can be 
exploited to cause heap-based buffer overflows.

Successful exploitation of vulnerability #2 may allow execution of arbitrary code.

Fixed in the git repository.

@maintainer(s): after the bump, in case we need to stabilize the package, please say explicitly if it is ready for the stabilization or not.

sounds like libav stuff, secunia link is about graphicsmagick, ffmpeg 1.2.6 seems to have the fixes; cc us back when you'll have figured what's wrong and what needs to be done
Comment 2 Yury German Gentoo Infrastructure gentoo-dev 2015-07-01 13:21:12 UTC
At this was fixed in 1.2.6, but will require a GLSA. Setting this to 548006, which when fixed will be one MONSTER GLSA.
