PLATFORM: Debian GNU/Linux 3.1 alias sarge (Woody is unaffected) Red Hat Desktop (v. 4) Red Hat Enterprise Linux AS, ES, WS (v. 4) DAMAGE: The kjs Javascript interpreter, used in the Konqueror web browser and in other parts of KDE, performs insufficient bounds checking when parsing UTF-8 encoded Uniform Resource Identifiers, which may lead to a heap based buffer overflow and the execution of arbitrary code. SOLUTION: Apply the available security updates. ______________________________________________________________________________ VULNERABILITY The risk is MEDIUM. An attacker could craft malicious ASSESSMENT: JavaScript code that would trigger this flaw and lead to execution of arbitrary code. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/q-106.shtml ORIGINAL BULLETIN: http://www.debian.org/security/2006/dsa-948 ADDITIONAL LINK: Red Hat Security Advisory RHSA-2006:0184 https://rhn.redhat.com/errata/RHSA-2006-0184.html CVE: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CVE-2006-0019 ______________________________________________________________________________ [***** Start Debian Security Advisory DSA 948 *****] DSA-948-1 kdelibs -- buffer overflow Date Reported: 20 Jan 2005 Affected Packages: kdelibs Vulnerable: Yes Security database references: In Mitre's CVE dictionary: CVE-2006-0019. More information: Maksim Orlovich discovered that the kjs Javascript interpreter, used in the Konqueror web browser and in other parts of KDE, performs insufficient bounds checking when parsing UTF-8 encoded Uniform Resource Identifiers, which may lead to a heap based buffer overflow and the execution of arbitrary code. The old stable distribution (woody) is not affected by this problem. For the stable distribution (sarge) this problem has been fixed in version 3.3.2-6.4 For the unstable distribution (sid) this problem will be fixed soon. We recommend that you upgrade your kdelibs package.
