Description Jan Lieskovsky 2010-11-23 12:32:50 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2009-5017 to
the following vulnerability:

Mozilla Firefox before 3.6 Beta 3 does not properly handle overlong UTF-8
encoding, which makes it easier for remote attackers to bypass cross-site
scripting (XSS) protection mechanisms via a crafted string, a different
vulnerability than CVE-2010-1210.
