Date Reported:

Security database references:
In Mitre's CVE dictionary: CVE-2007-6335, CVE-2007-6336.
More information:

Several remote vulnerabilities have been discovered in the Clam anti-virus toolkit. The Common Vulnerabilities and Exposures project identifies the following problems:

  • CVE-2007-6335

    It was discovered that an integer overflow in the decompression code for MEW archives may lead to the execution of arbitrary code.

  • CVE-2007-6336

    It was discovered that on off-by-one in the MS-ZIP decompression code may lead to the execution of arbitrary code.

The old stable distribution (sarge) is not affected by these problems. However, since the clamav version from Sarge cannot process all current Clam malware signatures any longer, support for the ClamAV in Sarge is now discontinued. We recommend to upgrade to the stable distribution or run a backport of the stable version.

For the stable distribution (etch) these problems have been fixed in version 0.90.1-3etch8.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your clamav packages.

Fixed in:

Debian GNU/Linux 4.0 (stable)
