Synopsis

The remote Debian host is missing a security-related update.

Description

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

- CVE-2007-4510 It was discovered that the RTF and RFC2397 parsers can be tricked into dereferencing a NULL pointer, resulting in denial of service.

- CVE-2007-4560 It was discovered that clamav-milter performs insufficient input sanitising, resulting in the execution of arbitrary shell commands.

The oldstable distribution (sarge) is only affected by a subset of the problems. An update will be provided later.

Solution

Upgrade the clamav packages.

For the stable distribution (etch) these problems have been fixed in version 0.90.1-3etch7.
