"USN-2102-1 fixed vulnerabilities in Firefox. The update introduced a
regression which could make Firefox crash under some circumstances.
This update fixes the problem.

We apologize for the inconvenience.

Christian Holler, Terrence Cole, Jesse Ruderman, Gary Kwong, Eric
Rescorla, Jonathan Kew, Dan Gohman, Ryan VanderMeulen, Carsten Book,
Andrew Sutherland, Byron Campen, Nicholas Nethercote, Paul Adenot,
David Baron, Julian Seward and Sotaro Ikeda discovered multiple memory
safety issues in Firefox. If a user were tricked in to opening a
specially crafted website, an attacker could potentially exploit these
to cause a denial of service via application crash, or execute
arbitrary code with the privileges of the user invoking Firefox.
(CVE-2014-1477, CVE-2014-1478)

Cody Crews discovered a method to bypass System Only
Wrappers. An attacker could potentially exploit this to
steal confidential data or execute code with the privileges
of the user invoking Firefox. (CVE-2014-1479)

Jordi Chancel discovered that the downloads dialog did not
implement a security timeout before button presses are
processed. An attacker could potentially exploit this to
conduct clickjacking attacks. (CVE-2014-1480)

Fredrik Lonnqvist discovered a use-after-free in Firefox.
An attacker could potentially exploit this to cause a denial
of service via application crash, or execute arbitrary code
with the priviliges of the user invoking Firefox.
(CVE-2014-1482)

Jordan Milne discovered a timing flaw when using
document.elementFromPoint and
document.caretPositionFromPoint on cross-origin iframes. An
attacker could potentially exploit this to steal
confidential imformation. (CVE-2014-1483)

Frederik Braun discovered that the CSP implementation in
Firefox did not handle XSLT stylesheets in accordance with
the specification, potentially resulting in unexpected
script execution in some circumstances (CVE-2014-1485)

Arthur Gerkis discovered a use-after-free in Firefox. An
attacker could potentially exploit this to cause a denial of
service via application crash, or execute arbitrary code
with the priviliges of the user invoking Firefox.
(CVE-2014-1486)

Masato Kinugawa discovered a cross-origin information leak
in web worker error messages. An attacker could potentially
exploit this to steal confidential information.
(CVE-2014-1487)

Yazan Tommalieh discovered that web pages could activate
buttons on the default Firefox startpage (about:home) in
some circumstances. An attacker could potentially exploit
this to cause data loss by triggering a session restore.
(CVE-2014-1489)

Soeren Balko discovered a crash in Firefox when terminating
web workers running asm.js code in some circumstances. An
attacker could potentially exploit this to execute arbitrary
code with the priviliges of the user invoking Firefox.
(CVE-2014-1488)

Several issues were discovered with ticket handling in NSS.
An attacker could potentially exploit these to cause a
denial of service or bypass cryptographic protection
mechanisms. (CVE-2014-1490, CVE-2014-1491)

Boris Zbarsky discovered that security restrictions on
window objects could be bypassed under certain
circumstances. (CVE-2014-1481).
