Updated kdelibs packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

The kdelibs packages provide libraries for the K Desktop Environment (KDE).

A flaw was found in the way the KDE CSS parser handled content for the CSS 'style' attribute. A remote attacker could create a specially crafted CSS equipped HTML page, which once visited by an unsuspecting user, could cause a denial of service (Konqueror crash) or, potentially, execute arbitrary code with the privileges of the user running Konqueror. (CVE-2009-1698)

A flaw was found in the way the KDE HTML parser handled content for the HTML 'head' element. A remote attacker could create a specially crafted HTML page, which once visited by an unsuspecting user, could cause a denial of service (Konqueror crash) or, potentially, execute arbitrary code with the privileges of the user running Konqueror.
(CVE-2009-1690)

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the KDE JavaScript garbage collector handled memory allocation requests. A remote attacker could create a specially crafted HTML page, which once visited by an unsuspecting user, could cause a denial of service (Konqueror crash) or, potentially, execute arbitrary code with the privileges of the user running Konqueror.
(CVE-2009-1687)

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The desktop must be restarted (log out, then log back in) for this update to take effect.

Several security issues have been discovered in kdelibs, core libraries from the official KDE release. 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.

This update fixes several security issues in the KDE 3 compatibility version of KHTML (CVE-2009-1725, CVE-2009-1690, CVE-2009-1687, CVE-2009-1698, CVE-2009-2537) which may lead to a denial of service or potentially even arbitrary code execution. In addition, the package was fixed to build with the latest version of automake, and the following fixes and improvements were merged from the Fedora 11 package: * slight speedup to /etc/profile.d/kde.sh,

  - fixed unowned directories, * fixed harmless (as the file     contents match) file conflicts with KDE 4.2.x, * fixed     build with GCC 4.4 (but this package is built with     Fedora 10's GCC 4.3.2), * moved Qt Designer plugins to     the runtime package as they can be needed at runtime     (e.g. by PyKDE programs), * kdelibs3-apidocs is now a     noarch subpackage.
