SpamAssassin: Long URI Denial of service

Background

SpamAssassin is an extensible email filter used to identify junk email.

Description

SpamAssassin does not correctly handle very long URIs when scanning emails.

Impact

An attacker could cause SpamAssassin to consume large amounts of CPU and memory resources by sending one or more emails containing very long URIs.

Workaround

There is no known workaround at this time.

Resolution

All SpamAssassin users should upgrade to the latest version.

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=mail-filter/spamassassin-3.1.8"
