CentOS 4 : spamassassin (CESA-2006:0543)

medium Nessus Plugin ID 21999

Synopsis

The remote CentOS host is missing a security update.

Description

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 determine 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.

Solution

Update the affected spamassassin package.
