Descriptions

In a non-standard configuration of Firefox, an integer overflow could have occurred based on network traffic (possibly under influence of a local unprivileged webpage), leading to an out-of-bounds write to privileged process memory.
*This bug only affects Firefox if a non-standard preference allowing non-HTTPS Alternate Services (`network.http.altsvc.oe`) is enabled.* This vulnerability affects Firefox < 118.

En una configuración no estándar de Firefox, podría haberse producido un desbordamiento de enteros basado en el tráfico de la red (posiblemente bajo la influencia de una página web local sin privilegios), lo que habría provocado una escritura fuera de límites en la memoria del proceso privilegiado. *Este error solo afecta a Firefox si está habilitada una preferencia no estándar que permite servicios alternativos no HTTPS (`network.http.altsvc.oe`).* Esta vulnerabilidad afecta a Firefox versión &lt; 118.
