Mozilla: Don't allow content to request favicons from non-whitelisted schemes (MFSA 2016-85)

Mozilla Firefox before 49.0 does not properly restrict the scheme in favicon requests, which might allow remote attackers to obtain sensitive information via unspecified vectors, as demonstrated by a jar: URL for a favicon resource.

Mozilla: iframe src fragment timing attack can reveal cross-origin data (MFSA 2016-85)

Mozilla Firefox before 49.0 allows remote attackers to bypass the Same Origin Policy via a crafted fragment identifier in the SRC attribute of an IFRAME element, leading to insufficient restrictions on link-color information after a document is resized.

Mozilla: Add-on update site certificate pin expiration (MFSA 2016-85, MFSA 2016-86)

Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 rely on unintended expiration dates for Preloaded Public Key Pinning, which allows man-in-the-middle attackers to spoof add-on updates by leveraging possession of an X.509 server certificate for addons.mozilla.org signed by an arbitrary built-in Certification Authority.

Mozilla: Crash in incremental garbage collection in JavaScript (MFSA 2016-71)

Use-after-free vulnerability in the js::PreliminaryObjectArray::sweep function in Mozilla Firefox before 48.0 allows remote attackers to execute arbitrary code via crafted JavaScript that is mishandled during incremental garbage collection.

graphite2: multiple font parsing vulnerabilities (Mozilla MFSA 2016-37)

The graphite2::Slot::getAttr function in Slot.cpp in Graphite 2 before 1.3.6, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted Graphite smart font, a different vulnerability than CVE-2016-2792.

Mozilla: Use-after-free and buffer overflow in Service Workers (MFSA 2016-42)

Race condition in the get implementation in the ServiceWorkerManager class in the Service Worker subsystem in Mozilla Firefox before 46.0 allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a crafted web site.

graphite2: multiple font parsing vulnerabilities (Mozilla MFSA 2016-37)

Heap-based buffer overflow in the graphite2::Slot::setAttr function in Graphite 2 before 1.3.6, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted Graphite smart font.

graphite2: multiple font parsing vulnerabilities (Mozilla MFSA 2016-37)

The graphite2::GlyphCache::Loader::Loader function in Graphite 2 before 1.3.6, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted Graphite smart font.

graphite2: multiple font parsing vulnerabilities (Mozilla MFSA 2016-37)

The graphite2::TtfUtil::CmapSubtable12Lookup function in Graphite 2 before 1.3.6, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted Graphite smart font, a different vulnerability than CVE-2016-2801.

graphite2: multiple font parsing vulnerabilities (Mozilla MFSA 2016-37)

Heap-based buffer overflow in the graphite2::vm::Machine::Code::Code function in Graphite 2 before 1.3.6, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted Graphite smart font.

graphite2: multiple font parsing vulnerabilities (Mozilla MFSA 2016-37)

The graphite2::FileFace::get_table_fn function in Graphite 2 before 1.3.6, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, does not initialize memory for an unspecified data structure, which allows remote attackers to cause a denial of service or possibly have unknown other impact via a crafted Graphite smart font.

Mozilla: Trailing whitespace in IP address hostnames can bypass same-origin policy (MFSA 2015-122)

Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 allow remote attackers to bypass the Same Origin Policy for an IP address origin, and conduct cross-site scripting (XSS) attacks, by appending whitespace characters to an IP address string.

Mozilla: disabling scripts in Add-on SDK panels has no effect (MFSA 2015-121)

The Add-on SDK in Mozilla Firefox before 42.0 misinterprets a "script: false" panel setting, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via inline JavaScript code that is executed within a third-party extension.

Mozilla Firefox before 42.0 on Android allows user-assisted remote attackers to bypass the Same Origin Policy and trigger (1) a download or (2) cached profile-data reading via a file: URL in a saved HTML document.

Mozilla Firefox before 42.0 on Android does not ensure that the address bar is restored upon fullscreen-mode exit, which allows remote attackers to spoof the address bar via crafted JavaScript code.

firefox: cross-origin restriction bypass using Fetch

The fetch API implementation in Mozilla Firefox before 41.0.2 does not restrict access to the HTTP response body in certain situations where user credentials are supplied but the CORS cross-origin request algorithm is improperly followed, which allows remote attackers to bypass the Same Origin Policy via a crafted web site.
