Descriptions

Buffer overflow in the idnsALookup function in dns_internal.cc in Squid 3.2 through 3.2.11 and 3.3 through 3.3.6 allows remote attackers to cause a denial of service (memory corruption and server termination) via a long name in a DNS lookup request.

Desbordamiento de búfer en la función idnsALookup en dns_internal.cc en Squid v3.2 hasta v3.2.11 y v3.3 hasta v3.3.6, lo que permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria o finalización de servicio) a través de un nombre largo en una petición “DNS lookup”.

A buffer overflow flaw was found in Squid's DNS lookup module. A remote attacker able to send HTTP requests to the Squid proxy could use this flaw to crash Squid.
