Description

Mozilla security researcher moz_bug_r_a4 reported an additional variation on the feed preview vulnerabilities fixed in Firefox 2.0.0.17. moz_bug_r_a4 demonstrated that it was still possible to use the feed preview as a vector for JavaScript privilege escalation. An attacker could use this issue to run arbitrary JavaScript with chrome privileges.

Firefox 3 is not affected by this issue.
