FreeBSD : rt42 -- denial-of-service attack via the email gateway (d1dfc4c7-8791-11e3-a371-6805ca0b3d42)

Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

The RT development team reports :

Versions of RT between 4.2.0 and 4.2.2 (inclusive) are vulnerable to a
denial-of-service attack via the email gateway; any installation which
accepts mail from untrusted sources is vulnerable, regardless of the
permissions configuration inside RT. This vulnerability is assigned
CVE-2014-1474.

This vulnerability is caused by poor parsing performance in the
Email::Address::List module, which RT depends on. We recommend that
affected users upgrade their version of Email::Address::List to v0.02
or above, which resolves the issue. Due to a communications mishap,
the release on CPAN will temporarily appear as 'unauthorized,' and the
command-line cpan client will hence not install it. We expect this to
be resolved shortly; in the meantime, the release is also available
from our server.
