Subject Name:            zlib
Subject Summary:         Compression Library
Subject Home:            http://www.zlib.net/
Subject Versions:        * <= 1.2.2

Vulnerability Id:        CVE-2005-2096
Vulnerability Scope:     global (not OpenPKG specific)

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

Description:
    Tavis Ormandy from Gentoo discovered a Denial of Service (DoS)
    vulnerability in the ZLib compression library [1] versions 1.2.x
    (older versions are not affected). An error in the handling of corrupt
    compressed data streams can result in a buffer being overflowed. By
    carefully crafting a corrupt compressed data stream, an attacker
    could overwrite data structures in a ZLib-using application.
