Mozilla: Out-of-bounds write in Cairo (MFSA 2014-41)

The sse2_composite_src_x888_8888 function in Pixman, as used in Cairo in Mozilla Firefox 28.0 and SeaMonkey 2.25 on Windows, allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds write and application crash) by painting on a CANVAS element.

HTTP/2: HEIST attack allows attackers to sniff TLS encrypted HTTP/2 traffic

The HTTP/2 protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack.

HTTPS: HEIST attack allows attackers to sniff TLS encrypted HTTP traffic

The HTTPS protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack.

Mozilla: Heap-buffer-overflow in nsBMPEncoder::AddImageFrame (MFSA 2016-85, MFSA 2016-86)

Heap-based buffer overflow in the nsBMPEncoder::AddImageFrame function in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to execute arbitrary code via a crafted image data that is mishandled during the encoding of an image frame to an image.

Mozilla: Heap-use-after-free in nsRefreshDriver::Tick (MFSA 2016-85, MFSA 2016-86)

Use-after-free vulnerability in the nsRefreshDriver::Tick function in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) by leveraging improper interaction between timeline destruction and the Web Animations model implementation.

Mozilla: Heap-use-after-free in mozilla::a11y::DocAccessible::ProcessInvalidationList (MFSA 2016-85, MFSA 2016-86)

Use-after-free vulnerability in the mozilla::a11y::DocAccessible::ProcessInvalidationList function in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via an aria-owns attribute.

Mozilla: global-buffer-overflow in mozilla::gfx::FilterSupport::ComputeSourceNeededRegions (MFSA 2016-85)

Buffer overflow in the mozilla::gfx::FilterSupport::ComputeSourceNeededRegions function in Mozilla Firefox before 49.0 allows remote attackers to execute arbitrary code by leveraging improper interaction between empty filters and CANVAS element rendering.

Mozilla: use-after-free in nsFrameManager::CaptureFrameState (MFSA 2016-85, MFSA 2016-86)

Use-after-free vulnerability in the nsFrameManager::CaptureFrameState function in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to execute arbitrary code by leveraging improper interaction between restyling and the Web Animations model implementation.

Mozilla: crash in mozilla::a11y::HyperTextAccessible::GetChildOffset (MFSA 2016-85)

The mozilla::a11y::HyperTextAccessible::GetChildOffset function in the accessibility implementation in Mozilla Firefox before 49.0 allows remote attackers to execute arbitrary code via a crafted web site.

Mozilla: Bad cast in nsImageGeometryMixin (MFSA 2016-85, MFSA 2016-86)

The nsImageGeometryMixin class in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 does not properly perform a cast of an unspecified variable during handling of INPUT elements, which allows remote attackers to execute arbitrary code via a crafted web site.

Mozilla: Out-of-bounds read in PropertyProvider::GetSpacingInternal (MFSA 2016-85)

The PropertyProvider::GetSpacingInternal function in Mozilla Firefox before 49.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via text runs in conjunction with a "display: contents" Cascading Style Sheets (CSS) property.

Mozilla: Heap-buffer-overflow in nsCaseTransformTextRunFactory::TransformString (MFSA 2016-85, MFSA 2016-86)

Heap-based buffer overflow in the nsCaseTransformTextRunFactory::TransformString function in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to cause a denial of service (boolean out-of-bounds write) or possibly have unspecified other impact via Unicode characters that are mishandled during text conversion.

Mozilla: Spoofing attack through text injection into internal error pages (MFSA 2016-83)

Mozilla Firefox before 48.0 does not properly set the LINKABLE and URI_SAFE_FOR_UNTRUSTED_CONTENT flags of about: URLs that are used for error pages, which makes it easier for remote attackers to conduct spoofing attacks via a crafted URL, as demonstrated by misleading text after an about:neterror?d= substring.

Mozilla Firefox before 48.0 on Android allows remote attackers to spoof the address bar via left-to-right characters in conjunction with a right-to-left character set.
