- BID-11729: Cyrus IMAPD Multiple Remote Vulnerabilities
- CVE-2004-1012: The argument parser of the PARTIAL command in Cyrus IMAP Server 2.2.6 and earlier allows remote authenticated users to execute arbitrary code via a certain command (body[p) that is treated as a different command (body.peek) and causes an index increment error that leads to an out-of-bounds memory corruption.
- CVE-2004-1013: The argument parser of the FETCH command in Cyrus IMAP Server 2.2.x through 2.2.8 allows remote authenticated users to execute arbitrary code via certain commands such as (1) body[p, (2) binary[p, or (3) binary[p) that cause an index increment error that leads to an out-of-bounds memory corruption.
