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

Vulnerability Id:        CVE-2005-1849
Vulnerability Scope:     global (not OpenPKG specific)

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

Description:
    A previous ZLib [1] update for CVE-2005-2096 fixed a Denial of Service
    (DoS) flaw that could allow a carefully crafted compressed stream to
    crash an application. While the original patch corrected the reported
    overflow, Markus Oberhumer discovered additional ways a stream could
    trigger an overflow.
