Subject Name:            Squid
Subject Summary:         World Wide Web Proxy Server
Subject Home:            http://www.squid-cache.org/
Subject Versions:        * <= 2.5.6

Vulnerability Id:        CVE-2004-0918
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           
Attack Impact:           denial of service

Description:
    According to an iDEFENSE security advisory [0], a denial of service
    (DoS) vulnerability exists in the Squid [1] web caching proxy.
    The "asn_parse_header" function in the SNMP module of Squid before
    version 2.4.STABLE7 allows remote attackers to cause a denial of
    service (server restart) via certain SNMP packets with negative
    length fields that causes a memory allocation error.
