Al llamar a `JS::CheckRegExpSyntax`, se podría haber establecido un error de sintaxis que terminaría llamando a `convertToRuntimeErrorAndClear`. Una ruta en la función podría intentar asignar memoria cuando no hay ninguna disponible, lo que habría provocado que una excepción de Falta de Memoria recién creada se…

Cuando `UpdateRegExpStatics` intentó acceder a `initialStringHeap`, es posible que ya se haya recolectado basura antes de ingresar a la función, lo que podría haber provocado un bloqueo explotable. Esta vulnerabilidad afecta a Firefox < 117, Firefox ESR < 115.2 y Thunderbird < 115.2.

En Windows, podría ocurrir un desbordamiento de enteros en `RecordedSourceSurfaceCreation`, lo que resultó en un desbordamiento del búfer que podría filtrar datos confidenciales que podrían haber llevado a un escape de la sandbox. *Este error sólo afecta a Firefox en Windows. Otros sistemas operativos no se ven…

Al crear una devolución de llamada a través de IPC para mostrar la ventana File Picker, se podrían haber creado varias devoluciones de llamada iguales a la vez y eventualmente todas destruidas simultáneamente tan pronto como finalice una de las devoluciones de llamada. Esto podría haber llevado a un uso después de la…

Al crear una devolución de llamada a través de IPC para mostrar la ventana Color Picker, se podrían haber creado varias devoluciones de llamada iguales a la vez y eventualmente todas destruidas simultáneamente tan pronto como finalice una de las devoluciones de llamada. Esto podría haber llevado a un uso después de la…

Al recibir datos de representación a través de IPC, `mStream` podría haberse destruido al inicializarse, lo que podría haber dado lugar a un uso después de la liberación que provocaría un bloqueo potencialmente explotable. Esta vulnerabilidad afecta a Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2 y…

Thunderbird allowed the Text Direction Override Unicode Character in filenames. An email attachment could be incorrectly shown as being a document file, while in fact it was an executable file. Newer versions of Thunderbird will strip the character and show the correct file extension. This vulnerability affects…

During the worker lifecycle, a use-after-free condition could have occurred, which could have led to a potentially exploitable crash. This vulnerability affects Firefox < 115.0.2, Firefox ESR < 115.0.2, and Thunderbird < 115.0.1.

Memory safety bugs present in Firefox 114, Firefox ESR 102.12, and Thunderbird 102.12. 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 < 115, Firefox ESR < 102.13, and…

When opening Diagcab files, Firefox did not warn the user that these files may contain malicious code. This vulnerability affects Firefox < 115, Firefox ESR < 102.13, and Thunderbird < 102.13.

A website could have obscured the fullscreen notification by using a URL with a scheme handled by an external program, such as a mailto URL.

Memory safety bugs present in Firefox 113, Firefox ESR 102.11, and Thunderbird 102.12. 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 ESR < 102.12, Firefox < 114, and…

The error page for sites with invalid TLS certificates was missing the activation-delay Firefox uses to protect prompts and permission dialogs from attacks that exploit human response time delays. If a malicious page elicited user clicks in precise locations immediately before navigating to a site with a certificate…

Similar to CVE-2023-28163, this time when choosing 'Save Link As', suggested filenames containing environment variable names would have resolved those in the context of the current user. *This bug only affects Firefox and Thunderbird on Windows. Other versions of Firefox and Thunderbird are unaffected.* This…

A newline in a filename could have been used to bypass the file extension security mechanisms that replace malicious file extensions such as .lnk with .download. This could have led to accidental execution of malicious code. *This bug only affects Firefox and Thunderbird on Windows. Other versions of Firefox and…

Protocol handlers `ms-cxh` and `ms-cxh-full` could have been leveraged to trigger a denial of service. *Note: This attack only affects Windows. Other operating systems are not affected.* This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.

A local attacker can trick the Mozilla Maintenance Service into applying an unsigned update file by pointing the service at an update file on a malicious SMB server. The update file can be replaced after the signature check, before the use, because the write-lock requested by the service does not work on a SMB server.…

An attacker could have caused an out of bounds memory access using WebGL APIs, leading to memory corruption and a potentially exploitable crash. *This bug only affects Firefox and Thunderbird for macOS. Other operating systems are unaffected.* This vulnerability affects Firefox < 112, Firefox ESR < 102.10, and…

Certain versions of HP PC Hardware Diagnostics Windows, HP Image Assistant, and HP Thunderbolt Dock G2 Firmware are potentially vulnerable to elevation of privilege.

Mozilla developers and community members Gabriele Svelto, Andrew Osmond, Emily McDonough, Sebastian Hengst, Andrew McCreight and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 112 and Firefox ESR 102.10. Some of these bugs showed evidence of memory corruption and we presume that with enough…

When reading a file, an uninitialized value could have been used as read limit. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.

An attacker could have positioned a `datalist` element to obscure the address bar. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.
