Simon Kilvington discovered that specially crafted PNG images can trigger
a heap overflow in libavcodec, the multimedia library of ffmpeg, which may
lead to the execution of arbitrary code.
xine-lib includes a local copy of libavcodec.
The old stable distribution (woody) isn’t affected by this problem.
For the stable distribution (sarge) this problem has been fixed in
version 1.0.1-1sarge2.
For the unstable distribution (sid) this problem has been fixed in
version 1.0.1-1.5.
We recommend that you upgrade your xine-lib package.
