Debian alerted vendor-sec to these issues.

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.

CAN-2005-0096

    Memory leak in the NTLM fakeauth_auth helper for Squid 2.5.STABLE7 and
    earlier allows remote attackers to cause a denial of service (memory
    consumption).

CAN-2005-0097

    The NTLM component in Squid 2.5.STABLE7 and earlier allows remote
    attackers to cause a denial of service (crash) via a malformed NTLM
    type 3 message.
