Subject Name:            gzip
Subject Summary:         De-/Compression with GZIP Algorithm
Subject Home:            http://www.gzip.org/
Subject Versions:        * <= 1.3.5

Vulnerability Id:        CVE-2005-1228
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           local system
Attack Impact:           manipulation of data

Description:
    According to a Debian bug report [0], Ulf Harnhammar discovered an
    input validation error in the GZip data compressor [1]. Because
    gzip(1) fails to properly validate file paths during decompression
    with the "-N" argument, a remote attacker using a malicious archive
    could corrupt arbitrary files with the privileges of the user that
    is running gzip(1). CVE-2005-1228
    
    Because the OpenPKG bootstrap package embeds GZip, it is affected as
    well. Please refer to OpenPKG-SA-2005.010-openpkg for details [3].
