"Several security vulnerabilities have been discovered in Squid, the
internet object cache, the popular WWW proxy cache. The Common
Vulnerabilities and Exposures project identifies the following
problems :

  - CVE-1999-0710
    It is possible to bypass access lists and scan arbitrary
    hosts and ports in the network through cachemgr.cgi,
    which is installed by default. This update disables this
    feature and introduces a configuration file
    (/etc/squid/cachemgr.conf) to control this behavior.

  - CAN-2004-0918

    The asn_parse_header function (asn1.c) in the SNMP
    module for Squid allows remote attackers to cause a
    denial of service via certain SNMP packets with negative
    length fields that causes a memory allocation error."
