    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.
