Hello,

A vulnerability [1] has been found in Dovecot, allowing a remote unauthenticated attacker to crash a Dovecot login process. To be vulnerable, Dovecot has to accept SSL/TLS connections while having disabled the use of SSLv3. It looks like the vulnerability also requires a recent (1.0.2+ ?) version of OpenSSL, but I can confirm that Arch is vulnerable.

Timo Sirainen has stated [2] that he will not release a new version for this specific issue only, so I think we should backport the fix [3].
