More information:

Two vulnerabilities have been discovered in Clam AntiVirus, the antivirus scanner for Unix, designed for integration with mail servers to perform attachment scanning. The following problems were identified:

CAN-2005-2919
A potentially infinite loop could lead to a denial of service.
CAN-2005-2920
A buffer overflow could lead to a denial of service.

The old stable distribution (woody) does not contain ClamAV packages.

For the stable distribution (sarge) these problems have been fixed in version 0.84-2.sarge.4.

For the unstable distribution (sid) these problems have been fixed in version 0.87-1.

We recommend that you upgrade your clamav package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
