wordpress - several

Two XSS bugs and one potential information disclosure issue were discovered
in WordPress, a weblog manager.
The Common Vulnerabilities and Exposures project identifies the
following problems:

• CVE-2011-0700
  Input passed via the post title when performing a Quick Edit or
  Bulk Edit action and via the post_status, comment_status,
  and ping_status parameters is not properly sanitised before being used.
  Certain input passed via tags in the tags meta-box is not properly sanitised
  before being returned to the user.
• CVE-2011-0701
  WordPress incorrectly enforces user access restrictions when accessing posts
  via the media uploader and can be exploited to disclose the contents
  of e.g. private or draft posts.

The oldstable distribution (lenny) is not affected by these problems.

For the stable distribution (squeeze), these problems have been fixed in
version 3.0.5+dfsg-0+squeeze1.

For the testing distribution (wheezy), and the unstable distribution (sid),
these problems have been fixed in version 3.0.5+dfsg-1.

We recommend that you upgrade your wordpress packages.
