Ubuntu: Security update for Firefox

Henrik Skupin, Jesse Ruderman, and others discovered several memory corruption flaws in Firefox. If a user were tricked into opening a specially crafted web page, a remote attacker could cause Firefox to crash or potentially execute arbitrary code as the user invoking the program. David Bloom and Jordi Chancel discovered that Firefox did not always properly handle the <select> element. A remote attacker could exploit this to conduct URL spoofing and clickjacking attacks. Collin Jackson discovered that Firefox did not properly follow the HTML5 specification for document.domain behavior. A remote attacker could exploit this to conduct cross-site scripting (XSS) attacks via javascript execution.

Johnny Stenback discovered that Firefox did not properly perform security checks on tests methods for DOMWindowUtils. Alice White discovered that the security checks for GetProperty could be bypassed when using JSAPI. If a user were tricked into opening a specially crafted web page, a remote attacker could exploit this to execute arbitrary code as the user invoking the program. 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.

Mariusz Mlynski and others discovered several flays in Firefox that allowed a remote attacker to conduct cross-site scripting (XSS) attacks. Abhishek Arya, Atte Kettunen and others discovered several memory flaws in Firefox when using the Address Sanitizer tool. If a user were tricked into opening a specially crafted web page, a remote attacker could cause Firefox to crash or potentially execute arbitrary code as the user invoking the program.

Details:

Henrik Skupin, Jesse Ruderman, Christian Holler, Soroush Dalili and others
discovered several memory corruption flaws in Firefox. If a user were
tricked into opening a specially crafted web page, a remote attacker could
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)

David Bloom and Jordi Chancel discovered that Firefox did not always
properly handle the <select> element. A remote attacker could exploit this
to conduct URL spoofing and clickjacking attacks. (CVE-2012-3984)

Collin Jackson discovered that Firefox did not properly follow the HTML5
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 tests methods for DOMWindowUtils. (CVE-2012-3986)

Alice White discovered that the security checks for GetProperty could be
bypassed when using JSAPI. If a user were tricked into opening a specially
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)

Mariusz Mlynski and others discovered several flays in Firefox that allowed
a remote attacker to conduct cross-site scripting (XSS) attacks.
(CVE-2012-3993, CVE-2012-3994, CVE-2012-4184)

Abhishek Arya, Atte Kettunen and others discovered several memory flaws in
Firefox when using the Address Sanitizer tool. If a user were tricked into
opening a specially crafted web page, a remote attacker could cause Firefox
to crash or potentially execute arbitrary code as the user invoking the
program. (CVE-2012-3990, CVE-2012-3995, CVE-2012-4179, CVE-2012-4180,
CVE-2012-4181, CVE-2012-4182, CVE-2012-4183, CVE-2012-4185, CVE-2012-4186,
