Description Vincent Danen 2011-05-19 22:27:26 UTC

Dovecot has released version 1.2.17 [1] and 2.0.13 [2] to address a potential crash, and possibly mailbox corruption, when dovecot parsed header names that contained NUL characters.  This was due to a pointer possibly pointing past allocated memory.  An upstream patch [3] is available.
