Mozilla Firefox is an open source web browser. XULRunner provides the
XUL Runtime environment for Mozilla Firefox.
Several flaws were found in the processing of malformed web content. A
web page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user
running Firefox. (CVE-2012-3982, CVE-2012-3988, 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,
Two flaws in Firefox could allow a malicious website to bypass
intended restrictions, possibly leading to information disclosure, or
Firefox executing arbitrary code. Note that the information disclosure
issue could possibly be combined with other flaws to achieve arbitrary
code execution. (CVE-2012-3986, CVE-2012-3991)
Multiple flaws were found in the location object implementation in
Firefox. Malicious content could be used to perform cross-site
scripting attacks, script injection, or spoofing attacks.
(CVE-2012-1956, CVE-2012-3992, CVE-2012-3994)
Two flaws were found in the way Chrome Object Wrappers were
implemented. Malicious content could be used to perform cross-site
scripting attacks or cause Firefox to execute arbitrary code.
For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 10.0.8 ESR.
This update also fixes the following bug :
- In certain environments, storing personal Firefox
configuration files (~/.mozilla/) on an NFS share, such
as when your home directory is on a NFS share, led to
Firefox functioning incorrectly, for example, navigation
buttons not working as expected, and bookmarks not
saving. This update adds a new configuration option,
storage.nfs_filesystem, that can be used to resolve this
