An issue was discovered in Squid 2.x, 3.x, and 4.x through 4.8. Due to incorrect data management, it is vulnerable to information disclosure when processing HTTP Digest Authentication. Nonce tokens contain the raw byte value of a pointer that sits within heap memory allocation. This information reduces ASLR protections and may aid attackers isolating memory areas to target for remote code execution attacks.

Se descubrió un problema en Squid versiones 2.x, 3.x y versiones 4.x hasta 4.8. Debido a una gestión de datos incorrecta, es vulnerable a una divulgación de información cuando se procesa HTTP Digest Authentication. Los tokens Nonce contienen el valor de byte sin procesar de un puntero que se encuentra dentro de la asignación de memoria heap. Esta información reduce las protecciones de ASLR y puede ayudar a atacantes a aislar áreas de memoria para apuntar ataques de ejecución de código remota.
