NVD Description

Note: Versions mentioned in the description apply only to the upstream cyrus-imapd-utils package and not the cyrus-imapd-utils package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. There is heap exposure in nested MIME comment parsing. An authenticated IMAP user could craft an email message containing an RFC 822 comment ending with a backslash. When parsing the message, the server would read past the message's end in memory, and read into the heap, returning the read content to the user.
