Description

An updated spamassassin package that fixes a denial of service bug when parsing malformed messages is now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

SpamAssassin provides a way to reduce unsolicited commercial email (SPAM) from incoming email.

A denial of service bug has been found in SpamAssassin. An attacker could construct a message in such a way that would cause SpamAssassin to consume CPU resources. If a number of these messages were sent it could lead to a denial of service, potentially preventing the delivery or filtering of email. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-1266 to this issue.

SpamAssassin version 3.0.4 additionally solves a number of bugs including: - #156390 Spamassassin consumes too much memory during learning - #155423 URI blacklist spam bypass - #147464 Users may now disable subject rewriting - Smarter default Bayes scores - Numerous other bug fixes that improve spam filter accuracy and safety

For full details, please refer to the change details of 3.0.2, 3.0.3, and 3.0.4 in SpamAssassin
