CVE-2014-6270

Error de superación de límite (off-by-one) en la función snmpHandleUdp en snmp_core.cc en Squid 2.x y 3.x, cuando un puerto SNMP está configurado, permite a atacantes remotos causar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de una solicitud UDP SNMP manipulada, lo que provoca un desbordamiento de buffer basado en memoria dinámica.

Due to incorrect state management, Squid before 3.3.12 is vulnerable to a denial of service attack when processing certain HTTPS requests if the SSL-Bump feature is enabled. Matthew Daley discovered that Squid 3 did not properly perform input validation in request parsing. A remote attacker could send crafted Range requests to cause a denial of service. Due to incorrect buffer management Squid can be caused by an attacker to write outside its allocated SNMP buffer. Due to incorrect bounds checking Squid pinger binary is vulnerable to denial of service or information leak attack when processing larger than normal ICMP or ICMPv6 packets. Due to incorrect input validation Squid pinger binary is vulnerable to denial of service or information leak attacks when processing ICMP or ICMPv6 packets.
