Background
==========

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

Affected packages
=================

  1  mail-filter/spamassassin       < 3.1.8                   >= 3.1.8

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
