- ------------------------------------------------------------------------

Package : libtk-img
Vulnerability : buffer overflows
Problem type : local (remote)
Debian-specific: no
CVE Ids : CVE-2007-5137 CVE-2007-5378
Debian Bug : 519072

Two buffer overflows have been found in the GIF image parsing code of
Tk, a cross-platform graphical toolkit, which could lead to the execution
of arbitrary code. The Common Vulnerabilities and Exposures project
identifies the following problems:


CVE-2007-5137

It was discovered that libtk-img is prone to a buffer overflow via
specially crafted multi-frame interlaced GIF files.

CVE-2007-5378

It was discovered that libtk-img is prone to a buffer overflow via
specially crafted GIF files with certain subimage sizes.


For the stable distribution (lenny), these problems have been fixed in
version 1.3-release-7+lenny1.

For the oldstable distribution (etch), these problems have been fixed in
version 1.3-15etch3.

For the testing distribution (squeeze) and the unstable distribution
(sid), these problems have been fixed in version 1.3-release-8.


We recommend that you upgrade your libtk-img packages.
