                    Mandrake Linux Security Update Advisory
    ________________________________________________________________________

    Package name: unzip
    Advisory ID: MDKSA-2003:073
    Date: July 7th, 2003

    Affected versions: 8.2, 9.0, 9.1, Corporate Server 2.1,
                            Multi Network Firewall 8.2
    ________________________________________________________________________

    Problem Description:

     A vulnerability was discovered in unzip 5.50 and earlier that allows
     attackers to overwrite arbitrary files during archive extraction by
     placing non-printable characters between two "." characters. These
     invalid characters are filtered which results in a ".." sequence.
     
     The patch applied to these packages prevents unzip from writing to
     parent directories unless the "-:" command line option is used.
