Please note that this regression only affects the oldstable distribution
(etch). For reference the original advisory text follows.


Several vulnerabilities have been discovered in wordpress, weblog
manager. The Common Vulnerabilities and Exposures project identifies the
following problems:

CVE-2008-6762

It was discovered that wordpress is prone to an open redirect
vulnerability which allows remote attackers to conduct phishing atacks.

CVE-2008-6767

It was discovered that remote attackers had the ability to trigger an
application upgrade, which could lead to a denial of service attack.

CVE-2009-2334

It was discovered that wordpress lacks authentication checks in the
plugin configuration, which might leak sensitive information.

CVE-2009-2854

It was discovered that wordpress lacks authentication checks in various
actions, thus allowing remote attackers to produce unauthorised edits or
additions.

CVE-2009-2851

It was discovered that the administrator interface is prone to a
cross-site scripting attack.

CVE-2009-2853

It was discovered that remote attackers can gain privileges via certain

directory traversal vulnerability, which could lead to the execution of
arbitrary code.

CVE-2008-4796

version is prone to the execution of arbitrary commands via shell
metacharacters in https URLs.

CVE-2008-5113

in certain dangerous situations, which makes it easier to perform
attacks via crafted cookies.


For the stable distribution (lenny), these problems have been fixed in
version 2.5.1-11+lenny1.

For the oldstable distribution (etch), these problems have been fixed in
version 2.0.10-1etch5.
