FreeBSD : rt42 -- denial-of-service attack via the email gateway (d1dfc4c7-8791-11e3-a371-6805ca0b3d42)
Medium Nessus Plugin ID 72155
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionThe 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.
SolutionUpdate the affected packages.
