Ubuntu Security Notice (C) 2004-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
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.
Update the affected packages.
Risk factor :
Medium / CVSS Base Score : 5.0
