USN19-1 : squid vulnerabilities

Vulnerability Assessment Summary
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)
