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.
An out-of-bounds write in the Graphite 2 library triggered with a maliciously crafted Graphite font. This results in a potentially exploitable crash. This issue was fixed in the Graphite 2 library as well as Mozilla products.
An out-of-bounds write during Base64 decoding operation in the Network Security Services (NSS) library due to insufficient memory being allocated to the buffer. This results in a potentially exploitable crash. The NSS library has been updated to fix this issue to address this issue and Firefox ESR 45.9 has been updated with NSS version 3.21.4.
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.
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.
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.
An out-of-bounds write vulnerability while decoding improperly formed BinHex format archives.
A buffer overflow vulnerability while parsing application/http-index-format format content when the header contains improperly formatted data. This allows for an out-of-bounds read of data from memory.
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.
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.
An out-of-bounds write in ClearKeyDecryptor while decrypting some Clearkey-encrypted media content. The ClearKeyDecryptor code runs within the Gecko Media Plugin (GMP) sandbox. If a second mechanism is found to escape the sandbox, this vulnerability allows for the writing of arbitrary data within memory, resulting in a potentially exploitable crash.
Three vulnerabilities were reported in the Libevent library that allow for out-of-bounds reads and denial of service (DoS) attacks. These were fixed in the Libevent library and these changes were ported to Mozilla code.
Fixed potential buffer overflows in generated Firefox code due to CVE-2016-6354 issue in Flex.
A vulnerability while parsing application/http-index-format format content where uninitialized values are used to create an array. This could allow the reading of uninitialized memory into the arrays affected.
A flaw in DRBG number generation within the Network Security Services (NSS) library where the internal state V does not correctly carry bits over. The NSS library has been updated to fix this issue to address this issue and Firefox ESR 45.9 has been updated with NSS version 3.21.4.
Mozilla developers and community members Christian Holler, Jon Coppeard, Marcia Knous, David Baron, Mats Palmgren, Ronald Crane, Bob Clary, and Chris Peterson reported memory safety bugs present in Firefox 52, Firefox ESR 45.8, and Firefox ESR 52. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code.
