It has been discovered that gst-plugins-good0.10, the GStreamer plugins from the "good" set, are prone to an integer overflow, when processing a large PNG file. This could lead to the execution of arbitrary code.
For the stable distribution (lenny), this problem has been fixed in version 0.10.8-4.1~lenny2.
For the oldstable distribution (etch), this problem has been fixed in version 0.10.4-4+etch1.
Packages for the s390 and hppa architectures will be released once they are available.
For the testing distribution (squeeze) and the unstable distribution (sid), this problem has been fixed in version 0.10.15-2.
We recommend that you upgrade your gst-plugins-good0.10 packages.
