Summary
unity-firefox-extension, webapps-greasemonkey, webaccounts-browser-extension update
Details

USN-2743-1 fixed vulnerabilities in Firefox. Future Firefox updates will require all addons be signed and unity-firefox-extension, webapps-greasemonkey and webaccounts-browser-extension will not go through the signing process. Because these addons currently break search engine installations (LP:

1069793), this update permanently disables the addons by removing them from

the system.

We apologize for any inconvenience.

Original advisory details:

Andrew Osmond, Olli Pettay, Andrew Sutherland, Christian Holler, David Major, Andrew McCreight, Cameron McCormack, Bob Clary and Randell Jesup 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-2015-4500, CVE-2015-4501)

André Bargull discovered that when a web page creates a scripted proxy for the window with a handler defined a certain way, a reference to the inner window will be passed, rather than that of the outer window. (CVE-2015-4502)

Felix Gröbert discovered an out-of-bounds read in the QCMS color management library 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 obtain sensitive information. (CVE-2015-4504)

Khalil Zhani discovered a buffer overflow when parsing VP9 content 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-2015-4506)

Spandan Veggalam discovered a crash while using the debugger API in some circumstances. If a user were tricked in to opening a specially crafted website whilst using the debugger, an attacker could potentially exploit this to execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2015-4507)

Juho Nurminen discovered that the URL bar could display the wrong URL in reader mode in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to conduct URL spoofing attacks. (CVE-2015-4508)

A use-after-free was discovered when manipulating HTML media content 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-2015-4509)

Looben Yang discovered a use-after-free when using a shared worker with IndexedDB 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-2015-4510)

Francisco Alonso discovered an out-of-bounds read during 2D canvas rendering 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-2015-4512)

Jeff Walden discovered that changes could be made to immutable properties in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to execute arbitrary script in a privileged scope. (CVE-2015-4516)

Ronald Crane reported multiple vulnerabilities. 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-2015-4517, CVE-2015-4521, CVE-2015-4522, CVE-2015-7174, CVE-2015-7175, CVE-2015-7176, CVE-2015-7177, CVE-2015-7180)

Mario Gomes discovered that dragging and dropping an image after a redirect exposes the redirected URL to scripts. An attacker could potentially exploit this to obtain sensitive information. (CVE-2015-4519)

Ehsan Akhgari discovered 2 issues with CORS preflight requests. An attacker could potentially exploit these to bypass CORS restrictions. (CVE-2015-4520)
