CentOS Errata and Security Advisory CESA-2006:0543
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.
