squid - multiple

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.

For the stable distribution (woody) these problems have been fixed in
version 2.4.6-2woody4.

For the unstable distribution (sid) these problems have been fixed in
version 2.5.7-1.

We recommend that you upgrade your squid package.
