CVE-2009-3012

Published: 31 August 2009

Mozilla Firefox 3.0.13 and earlier, 3.5, 3.6 a1 pre, and 3.7 a1 pre does not properly block data: URIs in Location headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Location header. NOTE: the JavaScript executes outside of the context of the HTTP site.

Notes

'firefox' source package on Ubuntu 8.04 LTS uses xulrunner 1.8.1
which is not-affected
per upstream: "Furthermore nome of the bugs you have referenced are
XSS. JavaScript executing within the context of the site that served it is
not cross-site anything."
