Description

 - ------------------------------------------------------------------------- Debian Security Advisory DSA-5708-1 [email protected] https://www.debian.org/security/ Moritz Muehlenhoff June 11, 2024 https://www.debian.org/security/faq

 Package : cyrus-imapd CVE ID : CVE-2024-34055

 Damian Poddebniak discovered that the Cyrus IMAP server didn't restrict memory allocation for some command arguments which may result in denial of service. This update backports new config directives which allow to configure limits, additional details can be found at:

 https://www.cyrusimap.org/3.6/imap/download/release-notes/3.6/x/3.6.5.html

 These changes are too intrusive to be backported to the version of Cyrus in the oldstable distribution (bullseye). If the IMAP server is used by untrusted users an update to Debian stable/bookworm is recommended.
 In addition the version of cyrus-imapd in bullseye-backports will be updated with a patch soon.

 For the stable distribution (bookworm), this problem has been fixed in version 3.6.1-4+deb12u2.

 We recommend that you upgrade your cyrus-imapd packages.

 For the detailed security status of cyrus-imapd please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/cyrus-imapd
