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.
