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

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

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

USN-2505-1 introduced a regression in Firefox.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

USN-2505-1 fixed vulnerabilities in Firefox. This update removed the
deprecated "-remote" command-line switch that some older software still
depends on. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

 Matthew Noorenberghe discovered that whitelisted Mozilla domains could
 make UITour API calls from background tabs. If one of these domains were
 compromised and open in a background tab, an attacker could potentially
 exploit this to conduct clickjacking attacks. (CVE-2015-0819)
 
 Jan de Mooij discovered an issue that affects content using the Caja
 Compiler. If web content loads specially crafted code, this could be used
 to bypass sandboxing security measures provided by Caja. (CVE-2015-0820)
 
 Armin Razmdjou discovered that opening hyperlinks with specific mouse
 and key combinations could allow a Chrome privileged URL to be opened
 without context restrictions being preserved. If a user were tricked in to
 opening a specially crafted website, an attacker could potentially exploit
 this to bypass security restrictions. (CVE-2015-0821)
 
 Armin Razmdjou discovered that contents of locally readable files could
 be made available via manipulation of form autocomplete in some
 circumstances. If a user were tricked in to opening a specially crafted
 website, an attacker could potentially exploit this to obtain sensitive
 information. (CVE-2015-0822)
 
 Atte Kettunen discovered a use-after-free in the OpenType Sanitiser (OTS)
 in some circumstances. If a user were tricked in to opening a specially
 crafted website, an attacker could potentially exploit this to cause a
 denial of service via application crash. (CVE-2015-0823)
 
 Atte Kettunen discovered a crash when drawing images using Cairo in some
 circumstances. If a user were tricked in to opening a specially crafted
 website, an attacker could potentially exploit this to cause a denial of
 service. (CVE-2015-0824)
 
 Atte Kettunen discovered a buffer underflow during playback of MP3 files
 in some circumstances. If a user were tricked in to opening a specially
 crafted website, an attacker could potentially exploit this to obtain
 sensitive information. (CVE-2015-0825)
 
 Atte Kettunen discovered a buffer overflow during CSS restyling in some
 circumstances. If a user were tricked in to opening a specially crafted
 website, an attacker could potentially exploit this to cause a denial of
 service via application crash, or execute arbitrary code with the
 privileges of the user invoking Firefox. (CVE-2015-0826)
 
 Abhishek Arya discovered an out-of-bounds read and write when rendering
 SVG content in some circumstances. If a user were tricked in to opening
 a specially crafted website, an attacker could potentially exploit this
 to obtain sensitive information. (CVE-2015-0827)
 
 A buffer overflow was discovered in libstagefright during video playback
 in some circumstances. If a user were tricked in to opening a specially
 crafted website, an attacker could potentially exploit this to cause a
 denial of service via application crash, or execute arbitrary code with
 the privileges of the user invoking Firefox. (CVE-2015-0829)
 
 Daniele Di Proietto discovered that WebGL could cause a crash in some
 circumstances. If a user were tricked in to opening a specially crafted
 website, an attacker could potentially exploit this to cause a denial of
 service. (CVE-2015-0830)
 
 Paul Bandha discovered a use-after-free in IndexedDB. If a user were
 tricked in to opening a specially crafted website, an attacker could
 potentially exploit this to cause a denial of service via application
 crash, or execute arbitrary code with the privileges of the user invoking
 Firefox. (CVE-2015-0831)
 
 Muneaki Nishimura discovered that a period appended to a hostname could
 bypass key pinning and HSTS in some circumstances. A remote attacker could
 potentially exloit this to conduct a Man-in-the-middle (MITM) attack.
 (CVE-2015-0832)
 
 Alexander Kolesnik discovered that Firefox would attempt plaintext
 connections to servers when handling turns: and stuns: URIs. A remote
 attacker could potentially exploit this by conducting a Man-in-the-middle
 (MITM) attack in order to obtain credentials. (CVE-2015-0834)
  
 Carsten Book, Christoph Diehl, Gary Kwong, Jan de Mooij, Liz Henry, Byron
 Campen, Tom Schuster, Ryan VanderMeulen, Christian Holler, Jesse Ruderman,
 Randell Jesup, Robin Whittleton, Jon Coppeard, and Nikhil Marathe
 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-2015-0835, CVE-2015-0836)

Update instructions:

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

Ubuntu 14.10:
  firefox                         36.0.1+build2-0ubuntu0.14.10.1

Ubuntu 14.04 LTS:
  firefox                         36.0.1+build2-0ubuntu0.14.04.1

Ubuntu 12.04 LTS:
  firefox                         36.0.1+build2-0ubuntu0.12.04.1

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