clamav - null pointer dereference

A NULL pointer dereference has been discovered in the RAR VM of Clam
Antivirus (ClamAV) which allows user-assisted remote attackers to
cause a denial of service via a specially crafted RAR archives.

We are currently unable to provide fixed packages for the MIPS
architectures. Those packages will be installed in the security
archive when they become available.

The old stable distribution (sarge) is not affected by this problem.

For the stable distribution (etch) this problem has been fixed in
version 0.90.1-3etch4.

For the unstable distribution (sid) this problem has been fixed in
version 0.91-1.

We recommend that you upgrade your clamav packages.
