Details

Henrik Skupin, Jesse Ruderman, Christian Holler, Soroush Dalili and others

cause Firefox to crash or potentially execute arbitrary code as the user
invoking the program. (CVE-2012-3982, CVE-2012-3983, CVE-2012-3988,
CVE-2012-3989)

properly handle the element. A remote attacker could exploit this
to conduct URL spoofing and clickjacking attacks. (CVE-2012-3984)

specification for document.domain behavior. A remote attacker could exploit
this to conduct cross-site scripting (XSS) attacks via javascript
execution. (CVE-2012-3985)

Johnny Stenback discovered that Firefox did not properly perform security
checks on test methods for DOMWindowUtils. (CVE-2012-3986)

crafted web page, a remote attacker could exploit this to execute arbitrary
code as the user invoking the program. (CVE-2012-3991)

Mariusz Mlynski discovered a history state error in Firefox. A remote
attacker could exploit this to spoof the location property to inject script
or intercept posted data. (CVE-2012-3992)
