RHSA-2006-0543: spamassassin

Vulnerability Assessment Summary
Check for the version of the spamassassin packages

Detailed Explanation for this Vulnerability Assessment

Updated spamassassin packages that fix an arbitrary code execution flaw
are 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 flaw was found with the way the Spamassassin spamd daemon processes the
virtual pop username passed to it. If a site is running spamd with both the
--vpopmail and --paranoid flags, it is possible for a remote user with the
ability to connect to the spamd daemon to execute arbitrary commands as
the user running the spamd daemon. (CVE-2006-2447)

Note: None of the IMAP or POP servers shipped with Red Hat Enterprise Linux
4 support vpopmail delivery. Running spamd with the --vpopmail and
--paranoid flags is uncommon and not the default startup option as shipped
with Red Hat Enterprise Linux 4.

Spamassassin, as shipped in Red Hat Enterprise Linux 4, performs RBL
lookups against visi.com to help acertain if an email is spam. However,
this DNS RBL has recently disappeared, resulting in mail filtering delays
and timeouts.

Users of SpamAssassin should upgrade to these updated packages containing
version 3.0.6 and backported patches, which are not vulnerable to these
issues.
