CVE-2016-2818

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 47.0 and Firefox ESR 45.x before 45.2 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Multiple flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox (CVE-2016-2818, CVE-2016-2819, CVE-2016-2821, CVE-2016-2822, CVE-2016-2828, CVE-2016-2831).

This update provides the next stable branch of Firefox, version 45.2.0.

Multiple flaws were found in the processing of malformed web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird (CVE-2016-2805, CVE-2016-2807, CVE-2016-2818).

This update provides the next stable branch of Thunderbird, version 45.2.0.

Christian Holler, Gary Kwong, Jesse Ruderman, Tyson Smith, Timothy Nikkel, Sylvestre Ledru, Julian Seward, Olli Pettay, Karl Tomlinson, Christoph Diehl, Julian Hector, Jan de Mooij, Mats Palmgren, and Tooru Fujisawa 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. (CVE-2016-2815, CVE-2016-2818)

A buffer overflow was discovered when parsing HTML5 fragments 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. (CVE-2016-2819)

A use-after-free was discovered in contenteditable mode 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. (CVE-2016-2821)

Jordi Chancel discovered a way to use a persistent menu within a <select> element and place this in an arbitrary location. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to spoof the addressbar contents. (CVE-2016-2822)

Armin Razmdjou that the location.host property can be set to an arbitrary string after creating an invalid data: URI. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass some same-origin protections. (CVE-2016-2825)

A use-after-free was discovered when processing WebGL 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. (CVE-2016-2828)

Tim McCormack discovered that the permissions notification can show the wrong icon when a page requests several permissions in quick succession. An attacker could potentially exploit this by tricking the user in to giving consent for access to the wrong resource. (CVE-2016-2829)

It was discovered that a pointerlock can be created in a fullscreen window without user consent in some circumstances, and this pointerlock cannot be cancelled without quitting Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service or conduct clickjacking attacks. (CVE-2016-2831)

John Schoenick discovered that CSS pseudo-classes can leak information about plugins that are installed but disabled. An attacker could potentially exploit this to fingerprint users. (CVE-2016-2832)

Matt Wobensmith discovered that Content Security Policy (CSP) does not block the loading of cross-domain Java applets when specified by policy. An attacker could potentially exploit this to bypass CSP protections and conduct cross-site scripting (XSS) attacks. (CVE-2016-2833)

In addition, multiple unspecified security issues were discovered in NSS. (CVE-2016-2834)

It was discovered that NSPR incorrectly handled memory allocation. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-1951)

Christian Holler, Gary Kwong, Jesse Ruderman, Tyson Smith, Timothy Nikkel, Sylvestre Ledru, Julian Seward, Olli Pettay, and Karl Tomlinson, discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code.
