uw-imap: buffer overflow in dmail and tmail

Multiple stack-based buffer overflows in (1) University of Washington IMAP Toolkit 2002 through 2007c, (2) University of Washington Alpine 2.00 and earlier, and (3) Panda IMAP allow (a) local users to gain privileges by specifying a long folder extension argument on the command line to the tmail or dmail program; and (b) remote attackers to execute arbitrary code by sending e-mail to a destination mailbox name composed of a username and '+' character followed by a long string, processed by the tmail or possibly dmail program.

uw-imap: NULL pointer dereference in smtp.c

smtp.c in the c-client library in University of Washington IMAP Toolkit 2007b allows remote SMTP servers to cause a denial of service (NULL pointer dereference and application crash) by responding to the QUIT command with a close of the TCP connection instead of the expected 221 response code.

libc-client: buffer overflow in rfc822_output_char / rfc822_output_data

Off-by-one error in the rfc822_output_char function in the RFC822BUFFER routines in the University of Washington (UW) c-client library, as used by the UW IMAP toolkit before imap-2007e and other applications, allows context-dependent attackers to cause a denial of service (crash) via an e-mail message that triggers a buffer overflow.

IMAP 4.1 BETA, and possibly other versions, does not properly handle the SIGABRT (abort) signal, which allows local users to crash the server (imapd) via certain sequences of commands, which causes a core dump that may contain sensitive password information.

Buffer overflow in University of Washington imapd version 4.7 allows users with a valid account to execute commands via LIST or other commands.

Buffer overflow in University of Washington c-client library (used by pine and other programs) allows remote attackers to execute arbitrary commands via a long X-Keywords header.

Arbitrary command execution via IMAP buffer overflow in authenticate command.

security flaw

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

security flaw

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.

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.

Buffer overflow in University of Washington's implementation of IMAP and POP servers.

Buffer overflow in the pop-2d POP daemon in the IMAP package allows remote attackers to gain privileges via the FOLD command.
