Details

Recently, two Denial of Service vulnerabilities have been discovered
in squid, a WWW proxy cache. Insufficient input validation in the NTLM
authentication handler allowed a remote attacker to crash the service
by sending a specially crafted NTLMSSP packet. Likewise, due to an
insufficient validation of ASN.1 headers, a remote attacker could
restart the server (causing all open connections to be dropped) by
sending certain SNMP packets with negative length fields.
