An updated spamassassin package that fixes a denial of service bug when parsing malformed messages is now available.
SpamAssassin provides a way to reduce unsolicited commercial email (SPAM) from incoming email. A denial of service bug has been found in SpamAssassin versions below 2.64. A malicious attacker could construct a message in such a way that would cause spamassassin to stop responding, potentially preventing the delivery or filtering of email. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0796 to this issue. Users of SpamAssassin should update to these updated packages which contain a backported patch and is not vulnerable to this issue.
