CVE-2004-1012: Carnegie Mellon University Cyrus Imap Server

High severity, CVSS 10.0. EPSS: 6% chance of exploitation in the next 30 days.

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.
