Bug 630684 – <net-mail/cyrus-imapd-3.0.4: use of uninitialized memory causes either denial of service or information leak

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Aleksandr Wagner (Kivak) 2017-09-11 14:45:29 UTC]

CVE-2017-14230 (https://nvd.nist.gov/vuln/detail/CVE-2017-14230):

In the mboxlist_do_find function in imap/mboxlist.c in Cyrus IMAP before 3.0.4, an off-by-one error in prefix calculation for the LIST command caused use of uninitialized memory, which might allow remote attackers to obtain sensitive information or cause a denial of service (daemon crash) via a 'LIST "" "Other Users"' command.

@arches, please test and mark stable as 3.0.4 is already in tree. 

@kivak, apologies to you sir, I missed the 'before' version part. Thanks for pointing this out!

Maintainer(s), please advise if you are ready for stabilization or call for stabilization yourself.

Has bug #604466 been addressed?
It makes cyrus-imapd completely unusable in any non-trivial configuration.

It has not, and we have just masked off the last working release. Can we please, please stable 3.0.5 instead?

GLSA Vote: No.


Bug will remain open to track cleanup (once maintainer is comfortable dropping it)
