Vulnerability Id:        CVE-2005-1228, CVE-2005-0953, CVE-2005-1260
Vulnerability Scope:     global (not OpenPKG specific)

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

Description:
    The vulnerabilities described by this text affect the OpenPKG
    bootstrap package's GZip and BZip2 embedded software. Similar
    advisories [0][1] describe the same vulnerabilities, although in
    context of the particular vendor software.
    
    According to a Debian bug report [2], Ulf Harnhammar discovered an
    input validation error in the GZip data compressor [3]. 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
    
    According to a BugTraq posting [5], Imran Ghory discovered a time
    of check time of use (TOCTOU) file mode vulnerability in the BZip2
    data compressor [6]. Because bzip2(1) does not safely restore the
    mode of a file undergoing compression or decompression, a malicious
    user can potentially change the mode of any file belonging to the
    user running bzip2(1). CVE-2005-0953
    
    In a unrelated BZip2 problem, a denial of service vulnerability
    was found in both the bzip2(1) program and its associated library
    libbz2(3). Specially crafted BZip2 archives lead to an infinite loop
    in the decompressor which results in an indefinitively large output
    file. This could be exploited to cause disk space exhaustion.
    CVE-2005-1260
