Format string vulnerability in the auth_debug function in Courier-IMAP 1.6.0 through 2.2.1 and 3.x through 3.0.3, when login debugging (DEBUG_LOGIN) is enabled, allows remote attackers to execute arbitrary code.

Integer overflow in imapparse.c for Cyrus IMAP server 1.4 and 2.1.10 allows remote attackers to execute arbitrary code via a large length value that facilitates a buffer overflow attack, a different vulnerability than CVE-2002-1347.

Multiple buffer overflows in (1) iso2022jp.c or (2) shiftjis.c for Courier-IMAP before 3.0.0, Courier before 0.45, and SqWebMail before 4.0.0 may allow remote attackers to execute arbitrary code "when Unicode character is out of BMP range."

c-client IMAP Client, as used in imap-2002b and Pine 4.53, allows remote malicious IMAP servers to cause a denial of service (crash) and possibly execute arbitrary code via certain large (1) literal and (2) mailbox size values that cause either integer signedness errors or integer overflow errors.

SQL injection vulnerability in the PostgreSQL auth module for courier 0.40 and earlier allows remote attackers to execute SQL code via the user name.

The default configuration of University of Washington IMAP daemon (wu-imapd), when running on a system that does not allow shell access, allows a local user with a valid IMAP account to read arbitrary files as that user.

Buffer overflow in University of Washington imap server (uw-imapd) imap-2001 (imapd 2001.315) and imap-2001a (imapd 2001.315) with legacy RFC 1730 support, and imapd 2000.287 and earlier, allows remote authenticated users to execute arbitrary code via a long BODY request.

Buffer overflows in Washington University imapd 2000a through 2000c could allow local users without shell access to execute code as themselves in certain configurations.

POP2 or POP3 server (pop3d) in imap-uw IMAP package on FreeBSD and other operating systems creates lock files with predictable names, which allows local users to cause a denial of service (lack of mail access) for other users by creating lock files for other mail boxes.

Cyrus 2.0.15, 2.0.16, and 1.6.24 on BSDi 4.2, with IMAP enabled, allows remote attackers to cause a denial of service (hang) using PHP IMAP clients.
