Synopsis
========
SpamAssassin, when running with certain options, could allow local or
even remote attackers to execute arbitrary commands, possibly as the
root user.
Background
==========
SpamAssassin is an extensible email filter used to identify junk email.
spamd is the daemonized version of SpamAssassin.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-filter/spamassassin < 3.1.3 >= 3.1.3
Description
===========
When spamd is run with both the "--vpopmail" (-v) and "--paranoid" (-P)
options, it is vulnerable to an unspecified issue.
Impact
======
With certain configuration options, a local or even remote attacker
could execute arbitrary code with the rights of the user running spamd,
which is root by default, by sending a crafted message to the spamd
daemon. Furthermore, the attack can be remotely performed if the
"--allowed-ips" (-A) option is present and specifies non-local
adresses. Note that Gentoo Linux is not vulnerable in the default
configuration.
Workaround
==========
Don't use both the "--paranoid" (-P) and the "--vpopmail" (-v) options.
Resolution
==========
All SpamAssassin users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-filter/spamassassin-3.1.3"
