CVE-2018-12375

Hay errores de seguridad de memoria en Firefox 61. Algunos de estos errores mostraron evidencias de corrupción de memoria y se entiende que, con el suficiente esfuerzo, algunos de estos podrían explotarse para ejecutar código arbitrario. La vulnerabilidad afecta a Firefox en versiones anteriores a la 62.

Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, or execute arbitrary code. It was discovered that if a user saved passwords before Firefox 58 and then later set a master password, an unencrypted copy of these passwords would still be accessible. A local user could exploit this to obtain sensitive information. Various other issues were also addressed.
