Descriptions

In violation of spec, cookie prefixes such as `__Secure` were being ignored if they were not correctly capitalized - by spec they should be checked with a case-insensitive comparison. This could have resulted in the browser not correctly honoring the behaviors specified by the prefix. This vulnerability affects Firefox < 127.

En violación de las especificaciones, los prefijos de cookies como `__Secure` se ignoraban si no estaban en mayúsculas correctamente; según las especificaciones, deberían verificarse con una comparación que no distinga entre mayúsculas y minúsculas. Esto podría haber provocado que el navegador no respetara correctamente los comportamientos especificados por el prefijo. Esta vulnerabilidad afecta a Firefox &lt; 127.

Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Lukas Bernhard discovered that Firefox did not properly manage memory during garbage collection. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code.
