DSA-1660-1 clamav -- null pointer dereference, resource exhaustation

Date Reported:
26 Oct 2008
Affected Packages:
clamav
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CVE-2008-3912, CVE-2008-3913, CVE-2008-3914.
More information:

Several denial-of-service vulnerabilities have been discovered in the ClamAV anti-virus toolkit:

Insufficient checking for out-of-memory conditions results in null pointer dereferences (CVE-2008-3912).

Incorrect error handling logic leads to memory leaks (CVE-2008-3913) and file descriptor leaks (CVE-2008-3914).

For the stable distribution (etch), these problems have been fixed in version 0.90.1dfsg-4etch15.

For the unstable distribution (sid) and the testing distribution (lenny), these problems have been fixed in version 0.94.dfsg-1.

We recommend that you upgrade your clamav package.

Fixed in:

Debian GNU/Linux 4.0 (etch)
