[Backports-security-announce] Security Update for uw-imap

Magnus Holmgren uploaded new packages for uw-imap which fixed the
following security problems:

CVE-2008-5005

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-2008-5006

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-2008-5514

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.

For the etch-backports distribution the problems have been fixed in
version 7:2007b~dfsg-4+lenny3~bpo40+1.

For the lenny distribution the problems have been fixed in version
