Cyrus IMAP username buffer overflow
| cyrus-imap-username-bo (18198) |  High Risk |
Description:
Cyrus IMAP Server allows a user to access Internet mail, news, and bulletin boards using Internet Message Access Protocol (IMAP) for Unix based operating systems. Cyrus IMAP Server is vulnerable to a stack-based buffer overflow in the PROXY and LOGIN commands. If the IMAPMAGICPLUS option is enabled, a remote attacker could send a long username to overflow a buffer and execute arbitrary code on the system.
