==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

Multiple security issues were fixed in Firefox.

Software Description:
- firefox: Mozilla Open Source web browser

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,
CVE-2012-4187, CVE-2012-4188)
