Multiple security issues have been found in Iceweasel, Debian's version of the Mozilla Firefox web browser: Multiple memory safety errors, missing input sanitising vulnerabilities, use-after-free vulnerabilities, buffer overflows and other programming errors may lead to the execution of arbitrary code, privilege escalation, information leaks or cross-site-scripting.

We're changing the approach for security updates for Iceweasel, Icedove and Iceape in stable-security: Instead of backporting security fixes, we now provide releases based on the Extended Support Release branch. As such, this update introduces packages based on Firefox 17 and at some point in the future we will switch to the next ESR branch once ESR 17 has reached it's end of life.

Some Xul extensions currently packaged in the Debian archive are not compatible with the new browser engine. Up-to-date and compatible versions can be retrieved from http://addons.mozilla.org as a short term solution. A solution to keep packaged extensions compatible with the Mozilla releases is still being sorted out.

We don't have the resources to backport security fixes to the Iceweasel release in oldstable-security any longer. If you're up to the task and want to help, please get in touch with team@security.debian.org. Otherwise, we'll announce the end of security support for Iceweasel, Icedove and Iceape in Squeeze in the next update round.

Olli Pettay, Jesse Ruderman, Boris Zbarsky, Christian Holler, Milan Sreckovic, Joe Drew, Andrew McCreight, Randell Jesup, Gary Kwong and Mats Palmgren discovered multiple memory safety issues affecting Firefox. If the user were tricked into opening a specially crafted page, an attacker could possibly exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2013-0788, CVE-2013-0789)

Ambroz Bizjak discovered an out-of-bounds array read in the CERT_DecodeCertPackage function of the Network Security Services (NSS) libary when decoding certain certificates. An attacker could potentially exploit this to cause a denial of service via application crash. (CVE-2013-0791)

Tobias Schula discovered an information leak in Firefox when the gfx.color_management.enablev4 preference is enabled. If the user were tricked into opening a specially crafted image, an attacker could potentially exploit this to steal confidential data. By default, the gfx.color_management.enablev4 preference is not enabled in Ubuntu. (CVE-2013-0792)

Mariusz Mlynski discovered that timed history navigations could be used to load arbitrary websites with the wrong URL displayed in the addressbar. An attacker could exploit this to conduct cross-site scripting (XSS) or phishing attacks.
(CVE-2013-0793)

It was discovered that the origin indication on tab-modal dialog boxes could be removed, which could allow an attacker's dialog to be displayed over another sites content. An attacker could exploit this to conduct phishing attacks. (CVE-2013-0794)

Cody Crews discovered that the cloneNode method could be used to bypass System Only Wrappers (SOW) to clone a protected node and bypass same-origin policy checks. An attacker could potentially exploit this to steal confidential data or execute code with the privileges of the user invoking Firefox. (CVE-2013-0795)

A crash in WebGL rendering was discovered in Firefox. An attacker could potentially exploit this to execute code with the privileges of the user invoking Firefox. This issue only affects users with Intel graphics drivers. (CVE-2013-0796)

    Jim Chen reported a memory safety problem that affects     Firefox for Android

    -. (CVE-2013-0790)

  - Security researcher Abhishek Arya (Inferno) of the     Google Chrome Security Team used the Address Sanitizer     tool to discover an out-of-bounds write in Cairo     graphics library. When certain values are passed to it     during rendering, Cairo attempts to use negative     boundaries or sizes for boxes, leading to a potentially     exploitable crash in some instances. (MFSA 2013-31 /     CVE-2013-0800)

  - Security researcher Frederic Hoguin discovered that the     Mozilla Maintenance Service on Windows was vulnerable to     a buffer overflow. This system is used to update     software without invoking the User Account Control (UAC)     prompt. The Mozilla Maintenance Service is configured to     allow unprivileged users to start it with arbitrary     arguments. By manipulating the data passed in these     arguments, an attacker can execute arbitrary code with     the system privileges used by the service. This issue     requires local file system access to be exploitable.
    (MFSA 2013-32 / CVE-2013-0799)

  - Security researcher Shuichiro Suzuki of the     Fourteenforty Research Institute reported the app_tmp     directory is set to be world readable and writeable by     Firefox for Android. This potentially allows for     third-party applications to replace or alter Firefox     add-ons when downloaded because they are temporarily     stored in the app_tmp directory before installation.
    (MFSA 2013-33 / CVE-2013-0798)

    This vulnerability only affects Firefox for Android.

  - Security researcher Ash reported an issue with the     Mozilla Updater. The Mozilla Updater can be made to load     a malicious local DLL file in a privileged context     through either the Mozilla Maintenance Service or     independently on systems that do not use the service.
    This occurs when the DLL file is placed in a specific     location on the local system before the Mozilla Updater     is run. Local file system access is necessary in order     for this issue to be exploitable. (MFSA 2013-34 /     CVE-2013-0797)

  - Security researcher miaubiz used the Address Sanitizer     tool to discover a crash in WebGL rendering when memory     is freed that has not previously been allocated. This     issue only affects Linux users who have Intel Mesa     graphics drivers. The resulting crash could be     potentially exploitable. (MFSA 2013-35 / CVE-2013-0796)

  - Security researcher Cody Crews reported a mechanism to     use the cloneNode method to bypass System Only Wrappers     (SOW) and clone a protected node. This allows violation     of the browser's same origin policy and could also lead     to privilege escalation and the execution of arbitrary     code. (MFSA 2013-36 / CVE-2013-0795)

  - Security researcher shutdown reported a method for     removing the origin indication on tab-modal dialog boxes     in combination with browser navigation. This could allow     an attacker's dialog to overlay a page and show another     site's content. This can be used for phishing by     allowing users to enter data into a modal prompt dialog     on an attacking, site while appearing to be from the     displayed site. (MFSA 2013-37 / CVE-2013-0794)

  - / CVE-2013-079: Security researcher Mariusz Mlynski     reported a method to use browser navigations through     history to load an arbitrary website with that page's     baseURI property pointing to another site instead of the     seemingly loaded one. The user will continue to see the     incorrect site in the addressbar of the browser. This     allows for a cross-site scripting (XSS) attack or the     theft of data through a phishing attack. (MFSA 2013-38)

  - Mozilla community member Tobias Schula reported that if     gfx.color_management.enablev4 preference is enabled     manually in about:config, some grayscale PNG images will     be rendered incorrectly and cause memory corruption     during PNG decoding when certain color profiles are in     use. A crafted PNG image could use this flaw to leak     data through rendered images drawing from random memory.
    By default, this preference is not enabled. (MFSA     2013-39 / CVE-2013-0792)

  - Mozilla community member Ambroz Bizjak reported an     out-of-bounds array read in the CERT_DecodeCertPackage     function of the Network Security Services (NSS) libary     when decoding a certificate. When this occurs, it will     lead to memory corruption and a non-exploitable crash.

The Mozilla Maintenance Service is configured to     allow unprivileged users to start it with arbitrary     arguments. By manipulating the data passed in these     arguments, an attacker can execute arbitrary code with     the system privileges used by the service. This issue     requires local file system access to be exploitable.
    (MFSA 2013-32 / CVE-2013-0799)

  - Security researcher Ash reported an issue with the     Mozilla Updater. The Mozilla Updater can be made to load     a malicious local DLL file in a privileged context     through either the Mozilla Maintenance Service or     independently on systems that do not use the service.
    This occurs when the DLL file is placed in a specific     location on the local system before the Mozilla Updater     is run. Local file system access is necessary in order     for this issue to be exploitable. (MFSA 2013-34 /     CVE-2013-0797)

  - Security researcher miaubiz used the Address Sanitizer     tool to discover a crash in WebGL rendering when memory     is freed that has not previously been allocated. This     issue only affects Linux users who have Intel Mesa     graphics drivers. The resulting crash could be     potentially exploitable. (MFSA 2013-35 / CVE-2013-0796)

  - Security researcher Cody Crews reported a mechanism to     use the cloneNode method to bypass System Only Wrappers     (SOW) and clone a protected node. This allows violation     of the browser's same origin policy and could also lead     to privilege escalation and the execution of arbitrary     code. (MFSA 2013-36 / CVE-2013-0795)

  - Security researcher shutdown reported a method for     removing the origin indication on tab-modal dialog boxes     in combination with browser navigation. This could allow     an attacker's dialog to overlay a page and show another     site's content. This can be used for phishing by     allowing users to enter data into a modal prompt dialog     on an attacking, site while appearing to be from the     displayed site. (MFSA 2013-37 / CVE-2013-0794)

  - Security researcher Mariusz Mlynski reported a method to     use browser navigations through history to load an     arbitrary website with that page's baseURI property     pointing to another site instead of the seemingly loaded     one. The user will continue to see the incorrect site in     the addressbar of the browser. This allows for a     cross-site scripting (XSS) attack or the theft of data     through a phishing attack. (MFSA 2013-38 /     CVE-2013-0793)

  - Mozilla community member Tobias Schula reported that if     gfx.color_management.enablev4 preference is enabled     manually in about:config, some grayscale PNG images will     be rendered incorrectly and cause memory corruption     during PNG decoding when certain color profiles are in     use. A crafted PNG image could use this flaw to leak     data through rendered images drawing from random memory.
    By default, this preference is not enabled. (MFSA     2013-39 / CVE-2013-0792)

  - Mozilla community member Ambroz Bizjak reported an     out-of-bounds array read in the CERT_DecodeCertPackage     function of the Network Security Services (NSS) libary     when decoding a certificate. When this occurs, it will     lead to memory corruption and a non-exploitable crash.
    (MFSA 2013-40 / CVE-2013-0791)
