[***** Start Debian Security Advisory DSA-1196-1 *****]
Several remote vulnerabilities have been discovered in the ClamAV malware scan engine, which may lead to the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems:
Damian Put discovered a heap overflow error in the script to rebuild PE files, which could lead to the execution of arbitrary code.
Damian Put discovered that missing input sanitising in the CHM handling code might lead to denial of service.
For the stable distribution (sarge) these problems have been fixed in version 0.84-2.sarge.11. Due to technical problems with the build host this update lacks a build for the Sparc architecture. It will be provided soon.
For the unstable distribution (sid) these problems have been fixed in version 0.88.5-1.
We recommend that you upgrade your clamav packages.
MD5 checksums of the listed files are available in the original advisory.
