Package        : spamassassin
Vulnerability  : mail header parsing error
Problem type   : remote DOS
Debian-specific: no
CVE Id(s)      : CAN-2005-1266
Debian Bug     : 314447

A vulnerability was recently found in the way that SpamAssassin parses
certain email headers. This vulnerability could cause SpamAssassin to
consume a large number of CPU cycles when processing messages containing
these headers, leading to a potential denial of service (DOS) attack. 

The version of SpamAssassin in the old stable distribution (woody) is
not vulnerable.

For the stable distribution (sarge), this problem has been fixed in
version 3.0.3-2. Note that packages are not yet ready for certain
architectures; these will be released as they become available.

For the unstable distribution (sid), this problem has been fixed in
version 3.0.4-1.

We recommend that you upgrade your sarge or sid spamassassin package.

Upgrade instructions
- - --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
