firefox vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 7.10
- Ubuntu 7.04
- Ubuntu 6.10
- Ubuntu 6.06 LTS
Software Description

Details
It was discovered that Firefox incorrectly associated redirected sites as the origin of “jar:” contents. A malicious web site could exploit this to modify or steal confidential data (such as passwords) from other web sites. (CVE-2007-5947)
Various flaws were discovered in the layout and JavaScript engines. By tricking a user into opening a malicious web page, an attacker could execute arbitrary code with the user’s privileges. (CVE-2007-5959)
Gregory Fleischer discovered that it was possible to use JavaScript to manipulate Firefox’s Referer header. A malicious web site could exploit this to conduct cross-site request forgeries against sites that relied only on Referer headers for protection from such attacks. (CVE-2007-5960)
