A buffer overflow can occur when the image renderer attempts to paint non-displayable SVG elements. This results in a potentially exploitable crash.

A use-after-free vulnerability in SMIL animation functions occurs when pointers to animation elements in an array are dropped from the animation controller while still in use. This results in a potentially exploitable crash.

A use-after-free vulnerability occurs during transaction processing in the editor during design mode interactions. This results in a potentially exploitable crash.

A buffer overflow in WebGL triggerable by web content, resulting in a potentially exploitable crash.

A use-after-free vulnerability occurs when redirecting focus handling which results in a potentially exploitable crash.

A use-after-free vulnerability occurs during certain text input selection resulting in a potentially exploitable crash.

A use-after-free vulnerability in frame selection triggered by a combination of malicious script content and key presses by a user. This results in a potentially exploitable crash.

A use-after-free vulnerability during XSLT processing due to the result handler being held by a freed handler during handling. This results in a potentially exploitable crash.

A use-after-free vulnerability during XSLT processing due to poor handling of template parameters. This results in a potentially exploitable crash.

A use-after-free vulnerability during XSLT processing due to a failure to propagate error conditions during matching while evaluating context, leading to objects being used when they no longer exist. This results in a potentially exploitable crash.

During DOM manipulations of the accessibility tree through script, the DOM tree can become out of sync with the accessibility tree, leading to memory corruption and a potentially exploitable crash.

A use-after-free vulnerability when holding a selection during scroll events. This results in a potentially exploitable crash.

A use-after-free vulnerability during changes in style when manipulating DOM elements. This results in a potentially exploitable crash.

An out-of-bounds write vulnerability while decoding improperly formed BinHex format archives.

An out-of-bounds read when an HTTP/2 connection to a servers sends "DATA" frames with incorrect data content. This leads to a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.

An out-of-bounds read during the processing of glyph widths during text layout. This results in a potentially exploitable crash and could allow an attacker to read otherwise inaccessible memory.

An out-of-bounds read while processing SVG content in "ConvolvePixel". This results in a crash and also allows for otherwise inaccessible memory being copied into SVG graphic content, which could then displayed. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.

Fixed potential buffer overflows in generated Firefox code due to CVE-2016-6354 issue in Flex.
