Description Tavis Ormandy (RETIRED) gentoo-dev 2006-02-16 05:08:09 UTC
Description:
A vulnerability have been reported in Dovecot, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to a double free error in pop3-login and imap-login when processing certain requests and can be exploited to crash the service.

Successful exploitation requires that "login_process_per_connection = no" has been set in the configuration file.

The vulnerability has been reported in versions prior to 1.0 beta3.

g2boojum: is beta3 suitable for arch stabilisation? or should the fixes be backported?

arches please test and mark stable, thx
Comment 6 Thierry Carrez (RETIRED) gentoo-dev 2006-02-21 10:42:22 UTC
DerCorny: Arches should be Cced in order to mark stable :P
1.0_beta3 is the stable target, please test and mark stable if not worse than the previous stable.

Ready for GLSA vote

The doc is quite explicit that setting login_process_per_connection=no is less secure, so I tend to vote no.
Comment 12 Stefan Cornelius (RETIRED) gentoo-dev 2006-03-04 08:48:56 UTC
voting no, too
Comment 13 Tavis Ormandy (RETIRED) gentoo-dev 2006-03-05 11:33:41 UTC
agree with Koon, NO.
Comment 14 Thierry Carrez (RETIRED) gentoo-dev 2006-03-05 13:12:25 UTC
Closing without GLSA
