Mozilla Firefox — свободный браузер на движке Gecko

Buffer overflow in the DirectWriteFontInfo::LoadFontFamilyData function in gfx/thebes/gfxDWriteFontList.cpp in Mozilla Firefox before 43.0 might allow remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted font-family name.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 43.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Heap-based buffer overflow in the stagefright::ESDS::parseESDescriptor function in libstagefright in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows remote attackers to execute arbitrary code via an invalid size field in an esds chunk in MPEG-4 video data, a related issue to CVE-2015-1539.

Integer overflow in the make_filter_table function in pixops/pixops.c in gdk-pixbuf before 2.31.5, as used in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 on Linux, Google Chrome on Linux, and other products, allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow and application crash) via crafted bitmap dimensions that are mishandled during scaling.

The PDF reader in Mozilla Firefox before 39.0.3, Firefox ESR 38.x before 38.1.1, and Firefox OS before 2.2 allows remote attackers to bypass the Same Origin Policy, and read arbitrary files or gain privileges, via vectors involving crafted JavaScript code and a native setter, as exploited in the wild in August 2015.

Use-after-free vulnerability in the XMLHttpRequest::Open implementation in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 might allow remote attackers to execute arbitrary code via a SharedWorker object that makes recursive calls to the open method of an XMLHttpRequest object.

The nsCSPHostSrc::permits function in dom/security/nsCSPUtils.cpp in Mozilla Firefox before 40.0 does not implement the Content Security Policy Level 2 exceptions for the blob, data, and filesystem URL schemes during wildcard source-expression matching, which might make it easier for remote attackers to conduct cross-site scripting (XSS) attacks by leveraging unexpected policy-enforcement behavior.

mar_read.c in the Updater in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows local users to gain privileges or cause a denial of service (out-of-bounds write) via a crafted name of a Mozilla Archive (aka MAR) file.

Heap-based buffer overflow in the resize_context_buffers function in libvpx in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows remote attackers to execute arbitrary code via malformed WebM video data.
