Pavel Kankovsky discovered that several overflows found in the libXpm library were also present in imlib and imlib2, imaging libraries for X11. An attacker could create a carefully crafted image file in such a way that it could cause an application linked with imlib or imlib2 to execute arbitrary code when the file was opened by a victim. The Common Vulnerabilities and Exposures project identifies the following problems:
Multiple heap-based buffer overflows. No such code is present in imlib2.
Multiple integer overflows in the imlib library.
For the stable distribution (woody) these problems have been fixed in version 1.0.5-2woody2.
For the unstable distribution (sid) these problems will be fixed soon.
We recommend that you upgrade your imlib2 packages.
MD5 checksums of the listed files are available in the original advisory.
