The remote host is affected by the vulnerability described in GLSA-200911-03 (UW IMAP toolkit: Multiple vulnerabilities)

    Multiple vulnerabilities were found in the UW IMAP toolkit:
    Aron Andersson and Jan Sahlin of Bitsec reported boundary errors in     the 'tmail' and 'dmail' utilities when processing overly long mailbox     names, leading to stack-based buffer overflows (CVE-2008-5005).
    An error in smtp.c in the c-client library was found, leading to a     NULL pointer dereference vulnerability (CVE-2008-5006).
    Ludwig     Nussel reported an off-by-one error in the rfc822_output_char()     function in the RFC822BUFFER routines in the c-client library, as used     by the UW IMAP toolkit (CVE-2008-5514).
  Impact :

    A remote attacker could send an e-mail to a destination mailbox name     composed of a username and '+' character followed by a long string,     possibly leading to the execution of arbitrary code. A local attacker     could gain privileges by specifying a long folder extension argument to     the tmail or dmail program. Furthermore, a remote attacker could send a     specially crafted mail message to the UW IMAP toolkit or another daemon     using the c-client library, leading to a Denial of Service. A remote     SMTP server could respond to the QUIT command with a close of the TCP     connection instead of the expected 221 response code, possibly leading     to a Denial of Service.
  Workaround :

    There is no known workaround at this time.

Insufficient buffer length checks in the imap client library may crash applications that use the library to print formatted email addresses.
The imap daemon itself is not affected but certain versions of e.g.
the php imap module are (CVE-2008-5514).

The client library could also crash when a rogue server unexpectedly closes the connection (CVE-2008-5006).

SANS reports :

The University of Washington IMAP library is a library implementing the IMAP mail protocol. University of Washington IMAP is exposed to a buffer overflow issue that occurs due to a boundary error within the rfc822_output_char function in the c-client library. The University of Washington IMAP library versions prior to 2007e are affected.

The remote host is affected by the vulnerability described in GLSA-201001-03 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the     CVE identifiers referenced below and the associated PHP release notes     for details.
  Impact :

    A context-dependent attacker could execute arbitrary code via a     specially crafted string containing an HTML entity when the mbstring     extension is enabled. Furthermore a remote attacker could execute     arbitrary code via a specially crafted GD graphics file.
    A remote attacker could also cause a Denial of Service via a malformed     string passed to the json_decode() function, via a specially crafted     ZIP file passed to the php_zip_make_relative_path() function, via a     malformed JPEG image passed to the exif_read_data() function, or via     temporary file exhaustion. It is also possible for an attacker to spoof     certificates, bypass various safe_mode and open_basedir restrictions     when certain criteria are met, perform Cross-site scripting attacks,     more easily perform SQL injection attacks, manipulate settings of other     virtual hosts on the same server via a malicious .htaccess entry when     running on Apache, disclose memory portions, and write arbitrary files     via a specially crafted ZIP archive. Some vulnerabilities with unknown     impact and attack vectors have been reported as well.
  Workaround :

    There is no known workaround at this time.

Update to new upstream version - 2007e. Contains fix for a security issue - buffer overflow in rfc822_output_char / rfc822_output_data (CVE-2008-5514).

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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.

SANS reports :

University of Washington 'tmail' and 'dmail' are mail deliver agents.
'tmail' and 'dmail' are exposed to local buffer overflow issues because they fail to perform adequate boundary checks on user-supplied data.

There is a flaw in the remote UW-IMAP server that allows a remote user to execute arbitrary code on the server.  The flaw is in the way that UW-IMAP handles malformed data sent to the 'rfc822_output_char' function of the 'c-client' library.  An attacker exploiting this flaw would only need the ability to send malformed data to the server process.
