Description: A weakness has been discovered in Konqueror, which can potentially be exploited by malicious people to conduct cross-site scripting attacks. The weakness is caused due to an error in the parsing of comments within title tags of an HTML document. Arbitrary HTML and script code in a comment tag is executed in a user's browser session when preceded by the corresponding closing title tag. Successful exploitation is possible on web sites that allow users to insert unsanitised HTML and script code within a comment into such a tag. The weakness is confirmed in Konqueror 3.5.5. Other versions may also be affected. Solution: Apply patch. ftp://ftp.kde.org/pub/kde/security_patches/post-3.5.6-kdelibs.diff Provided and/or discovered by: Originally discovered in Safari by Jose Avila III. Changelog: 2007-01-30: Added CVE reference. 2007-02-07: Updated "Description" and "Solution". Other References: KDE: http://www.kde.org/info/security/advisory-20070206-1.txt
