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.

The IMAP Client for Sylpheed 0.8.11 allows remote malicious IMAP servers to cause a denial of service (crash) via certain large literal size values that cause either integer signedness errors or integer overflow errors.

Pine 4.2.1 through 4.4.4 puts Unix usernames and/or uid into Sender: and X-Sender: headers, which could allow remote attackers to obtain sensitive information.

The c-client library in Internet Message Access Protocol (IMAP) dated before 2002 RC2, as used by Pine 4.20 through 4.44, allows remote attackers to cause a denial of service (client crash) via a MIME-encoded email with Content-Type header containing an empty boundary field.

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.

Pine 4.44 and earlier allows remote attackers to cause a denial of service (core dump and failed restart) via an email message with a From header that contains a large number of quotation marks (").

URL-handling code in Pine 4.43 and earlier allows remote attackers to execute arbitrary commands via a URL enclosed in single quotes and containing shell metacharacters (&).

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.

Vulnerability in (1) pine before 4.33 and (2) the pico editor, included with pine, allows local users local users to overwrite arbitrary files via a symlink attack.

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