kde4libs - several vulnerabilities

Several security issues have been discovered in kde4libs, core libraries
for all KDE 4 applications. The Common Vulnerabilities and Exposures
project identifies the following problems:

• CVE-2009-1690
  It was discovered that there is a use-after-free flaw in handling
  certain DOM event handlers. This could lead to the execution of
  arbitrary code, when visiting a malicious website.
• CVE-2009-1698
  It was discovered that there could be an uninitialised pointer when
  handling a Cascading Style Sheets (CSS) attr function call. This could
  lead to the execution of arbitrary code, when visiting a malicious
  website.
• CVE-2009-1687
  It was discovered that the JavaScript garbage collector does not handle
  allocation failures properly, which could lead to the execution of
  arbitrary code when visiting a malicious website.

The oldstable distribution (etch) does not contain kde4libs.

For the stable distribution (lenny), these problems have been fixed in
version 4:4.1.0-3+lenny1.

For the testing distribution (squeeze), these problems will be fixed
soon.

For the unstable distribution (sid), these problems have been fixed in
version 4:4.3.0-1.

We recommend that you upgrade your kde4libs packages.
