Due to large allocation checks in Angle for glsl shaders being too lenient a buffer overflow could have occured when allocating too much private shader memory on mac OS. *This bug only affects Firefox on macOS. Other operating systems are unaffected.* This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. Debido a que las grandes comprobaciones de asignación en Angle para que los sombreadores glsl sean demasiado indulgentes, se podría haber producido un desbordamiento del búfer al asignar demasiada memoria de sombreado privada en Mac OS. *Este error sólo afecta a Firefox en macOS. Otros sistemas operativos no se ven afectados.* Esta vulnerabilidad afecta a Firefox < 117, Firefox ESR < 115.2 y Thunderbird < 115.2. • https://bugzilla.mozilla.org/show_bug.cgi?id=1773874 https://www.mozilla.org/security/advisories/mfsa2023-34 https://www.mozilla.org/security/advisories/mfsa2023-36 https://www.mozilla.org/security/advisories/mfsa2023-38 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

On Windows, an integer overflow could occur in `RecordedSourceSurfaceCreation` which resulted in a heap buffer overflow potentially leaking sensitive data that could have led to a sandbox escape. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and 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 afectados.* Esta vulnerabilidad afecta a Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2 y Thunderbird < 115.2. • https://bugzilla.mozilla.org/show_bug.cgi?id=1846694 https://www.mozilla.org/security/advisories/mfsa2023-34 https://www.mozilla.org/security/advisories/mfsa2023-35 https://www.mozilla.org/security/advisories/mfsa2023-36 https://www.mozilla.org/security/advisories/mfsa2023-37 https://www.mozilla.org/security/advisories/mfsa2023-38 • CWE-190: Integer Overflow or Wraparound •

Excel `.xll` add-in files did not have a blocklist entry in Firefox's executable blocklist which allowed them to be downloaded without any warning of their potential harm. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. Los archivos complementarios `.xll` de Excel no tenían una entrada en la lista de bloqueo ejecutable de Firefox, lo que permitía descargarlos sin ninguna advertencia sobre su daño potencial. Esta vulnerabilidad afecta a Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2 y Thunderbird < 115.2.

When receiving rendering data over IPC `mStream` could have been destroyed when initialized, which could have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. 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.

CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2023-4574 – Mozilla: Memory corruption in IPC ColorPickerShownCallback
https://notcve.org/view.php?id=CVE-2023-4574
When creating a callback over IPC for showing the Color Picker window, multiple of the same callbacks could have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. 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 liberación que provocó un bloqueo potencialmente explotable. • https://bugzilla.mozilla.org/show_bug.cgi?id=1846688 https://www.mozilla.org/security/advisories/mfsa2023-34 https://www.mozilla.org/security/advisories/mfsa2023-35 https://www.mozilla.org/security/advisories/mfsa2023-36 https://www.mozilla.org/security/advisories/mfsa2023-37 https://www.mozilla.org/security/advisories/mfsa2023-38 https://access.redhat.com/security/cve/CVE-2023-4574 https://bugzilla.redhat.com/show_bug.cgi?id=2236072 • CWE-416: Use After Free •
