Mozilla Firefox — свободный браузер на движке Gecko

Memory safety bugs present in Firefox 124. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 125.

If an AlignedBuffer were assigned to itself, the subsequent self-move could result in an incorrect reference count and later use-after-free. This vulnerability affects Firefox < 125 and Firefox ESR < 115.10.

The executable file warning was not presented when downloading .xrm-ms files. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.* This vulnerability affects Firefox < 125 and Firefox ESR < 115.10.

The MarkStack assignment operator, part of the JavaScript engine, could access uninitialized memory if it were used in a self-assignment. This vulnerability affects Firefox < 125.

On 32-bit versions there were integer-overflows that led to an out-of-bounds-read that potentially could be triggered by a malformed OpenType font. This vulnerability affects Firefox < 125 and Firefox ESR < 115.10.

It was possible to mutate a JavaScript object so that the JIT could crash while tracing it. This vulnerability affects Firefox < 125.

An out-of-memory condition during object initialization could result in an empty shape list. If the JIT subsequently traced the object it would crash. This vulnerability affects Firefox < 125.

The JIT created incorrect code for arguments in certain cases. This led to potential use-after-free crashes during garbage collection. This vulnerability affects Firefox < 125 and Firefox ESR < 115.10.

A use-after-free could result if a JavaScript realm was in the process of being initialized when a garbage collection started. This vulnerability affects Firefox < 125.

GetBoundName could return the wrong version of an object when JIT optimizations were applied. This vulnerability affects Firefox < 125 and Firefox ESR < 115.10.
