    ===========================================================
    Ubuntu Security Notice USN-19-1 November 06, 2004
    squid vulnerabilities
    CAN-2004-0832, CAN-2004-0918
    ===========================================================

    A security issue affects the following Ubuntu releases:

    Ubuntu 4.10 (Warty Warthog)

    The following packages are affected:

    squid

    The problem can be corrected by upgrading the affected package to
    version 2.5.5-6ubuntu0.2. In general, a standard system upgrade is
    sufficient to effect the necessary changes.

    Details follow:

    Recently, two Denial of Service vulnerabilities have been discovered
    in squid, a WWW proxy cache. Insufficient input validation in the NTLM
    authentication handler allowed 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.
