Could a CVE be assigned for the following please?

Dovecot 2.1.11 was released and includes a fix for a crash
condition when the IMAP server was issued a SEARCH command with
multiple KEYWORD parameters.  An authenticated remote user could
use this flaw to crash Dovecot.

Thanks.

Please use CVE-2012-5620 for this issue.


We were discussing this issue too at [1] and think that it does only
affect the current connection, no subsequent (i.e. new) connections
are affected.

What's your opinion wrt this?

Upstream (Timo Sirainen) disputed the issue in the Debian BTS:
