Mozilla Firefox — свободный браузер на движке Gecko

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 Firefox before 42.0 and Firefox ESR 38.x before 38.4, when a Java plugin is enabled, allow remote attackers to cause a denial of service (incorrect garbage collection and application crash) or possibly execute arbitrary code via a crafted Java applet that deallocates an in-use JavaScript wrapper.

Heap-based buffer overflow in the ASN.1 decoder in Mozilla Network Security Services (NSS) before 3.19.2.1 and 3.20.x before 3.20.1, as used in Firefox before 42.0 and Firefox ESR 38.x before 38.4 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted OCTET STRING data.

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.

The (1) AddWeightedPathSegLists and (2) SVGPathSegListSMILType::Interpolate functions in Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 lack status checking, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted SVG document.

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.

Buffer overflow in the rx::TextureStorage11 class in ANGLE, as used in Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4, allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted texture data.

The CryptoKey interface implementation in Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 lacks status checking, which allows attackers to have an unspecified impact via vectors related to a cryptographic key.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The Reader View implementation in Mozilla Firefox before 42.0 has an improper whitelist, which makes it easier for remote attackers to bypass the Content Security Policy (CSP) protection mechanism and conduct cross-site scripting (XSS) attacks via vectors involving SVG animations and the about:reader URL.
