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)
