Advisories MDVSA-2009:146-1: imap

[paul]

Security vulnerabilities has been identified and fixed in University

of Washington IMAP Toolkit:

 

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 (CVE-2008-5005).

 

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 (CVE-2008-5006).

 

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 (CVE-2008-5514).

 

The updated packages have been patched to prevent this. Note that the

software was renamed to c-client starting from Mandriva Linux 2009.0

and only provides the shared c-client library for the imap functions

in PHP.

 

Update:

 

Packages for 2008.0 are provided for Corporate Desktop 2008.0

customers.
