firefox regression
==========================================================================

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

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

USN-2102-1 introduced a regression in Firefox.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

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.

Original advisory details:

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 L?nnqvist 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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.10:
firefox 27.0.1+build1-0ubuntu0.13.10.1

Ubuntu 12.10:
firefox 27.0.1+build1-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
firefox 27.0.1+build1-0ubuntu0.12.04.1

After a standard system update you need to restart Firefox to make
all the necessary changes.
