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. For the stable distribution (lenny), these problems have been fixed in version 4:3.5.10.dfsg.1-0lenny2. For the oldstable distribution (etch), these problems have been fixed in version 4:3.5.5a.dfsg.1-8etch2. For the testing distribution (squeeze) and the unstable distribution (sid), these problems will be fixed soon. We recommend that you upgrade your kdelibs packages.
