A compromised content process could have provided malicious data to `FilterNodeD2D1` resulting in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3. Un proceso de contenido comprometido podría haber proporcionado datos maliciosos a `FilterNodeD2D1`, lo que habría resultado en una escritura fuera de los límites, lo que habría provocado una falla potencialmente explotable en un proceso privilegiado. *Este error sólo afecta a Firefox en Windows. Otros sistemas operativos no se ven afectados.* Esta vulnerabilidad afecta a Firefox < 118, Firefox ESR < 115.3 y Thunderbird < 115.3. • https://bugzilla.mozilla.org/show_bug.cgi?id=1846683 https://www.mozilla.org/security/advisories/mfsa2023-41 https://www.mozilla.org/security/advisories/mfsa2023-42 https://www.mozilla.org/security/advisories/mfsa2023-43 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-4863
Heap buffer overflow in libwebp in Google Chrome prior to 116.0.5845.187 and libwebp 1.3.2 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: Critical) El desbordamiento del búfer de memoria en libwebp en Google Chrome anterior a 116.0.5845.187 y libwebp 1.3.2 permitía a un atacante remoto realizar una escritura en memoria fuera de los límites a través de una página HTML manipulada. (Severidad de seguridad de Chromium: crítica) A heap-based buffer flaw was found in the way libwebp, a library used to process "WebP" image format data, processes certain specially formatted WebP images. An attacker could use this flaw to crash or execute remotely arbitrary code in an application such as a web browser compiled with this library. Google Chromium WebP contains a heap-based buffer overflow vulnerability that allows a remote attacker to perform an out-of-bounds memory write via a crafted HTML page. • https://github.com/alsaeroth/CVE-2023-4863-POC https://github.com/mistymntncop/CVE-2023-4863 https://github.com/LiveOverflow/webp-CVE-2023-4863 https://github.com/bbaranoff/CVE-2023-4863 https://github.com/talbeerysec/BAD-WEBP-CVE-2023-4863 https://github.com/huiwen-yayaya/CVE-2023-4863 https://github.com/CrackerCat/CVE-2023-4863- https://github.com/sarsaeroth/CVE-2023-4863-POC http://www.openwall.com/lists/oss-security/2023/09/21/4 http://www.openwall.com/list • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

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 •
