squid vulnerabilities Detailed Explanation for this Vulnerability Assessment Summary : These remote packages are missing security patches : - squid - squid-cgi - squid-common - squidclient Description : Recently, two Denial of Service vulnerabilities have been discovered in squid, a WWW proxy cache. Insufficient input validation in the NTLM authentication handler permited 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. Solution : Upgrade to : - squid-2.5.5-6ubuntu0.2 (Ubuntu 4.10) - squid-cgi-2.5.5-6ubuntu0.2 (Ubuntu 4.10) - squid-common-2.5.5-6ubuntu0.2 (Ubuntu 4.10) - squidclient-2.5.5-6ubuntu0.2 (Ubuntu 4.10) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
