Description David Walser 2022-02-22 00:11:27 CET

Fedora has issued an advisory on February 19:
https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/WJZB45QBUN7CZFGOWCZYUYACNBTX7LVS/

The issues are fixed upstream in 3.0.16 and 3.2.8.

The first CVE may not affect us (it's not entirely clear), but the second one definitely does.

Mageia 8 is also affected.

Status comment: (none) => Fixed upstream in 3.0.16

Comment 1 Lewis Smith 2022-02-22 19:56:37 CET

No particular packager evident, so assigning this globally.

Debian-LTS has issued an advisory for the second issue today (June 20):

Comment 3 Nicolas Salguero 2022-06-21 10:40:01 CEST

Hi,

At least, Debian, OpenSUSE and upstream say CVE-2021-32056 only affects 3.2.x and above:

Best regards,

Suggested advisory:
========================

The updated packages fix a security vulnerability:

Cyrus IMAP before 3.4.2 allows remote attackers to cause a denial of service (multiple-minute daemon hang) via input that is mishandled during hash-table interaction. Because there are many insertions into a single bucket, strcmp becomes slow. (CVE-2021-33582)

Comment 5 Nicolas Salguero 2022-06-21 10:43:12 CEST

Regarding CVE-2021-32056, when I looked at the code, I did not find the affected code so I also think that CVE does not affect us.

Comment 6 Herman Viaene 2022-06-24 16:53:46 CEST

Selecting all four packages in QARepo gives:
lib64cyrus-imapd0-2.5.15-3.1.mga not found in the remote repository

Comment 7 David Walser 2022-06-24 16:58:38 CEST

There should be an 8 at the end of that name (mga8).
