Descriptions

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.
