Package        : squid
Vulnerability  : buffer overflow, integer overflow
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2005-0094 CAN-2005-0095

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

CAN-2005-0094

    "infamous41md" discovered a buffer overflow in the parser for
    Gopher responses which will lead to memory corruption and usually
    crash Squid.

CAN-2005-0095

    "infamous41md" discovered an integer overflow in the receiver of
    WCCP (Web Cache Communication Protocol) messages.  An attacker
    could send a specially crafted UDP datagram that will cause Squid
    to crash.

For the stable distribution (woody) these problems have been fixed in
version 2.4.6-2woody5.

For the unstable distribution (sid) these problems have been fixed in
version 2.5.7-4.

We recommend that you upgrade your squid package.

        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
