(cpio: Directory traversal vulnerability)

    A vulnerability has been found in cpio that can potentially allow
    a cpio archive to extract its files to an arbitrary directory of the
    creator's choice.
  
Impact :

    An attacker could create a malicious cpio archive which would
    create files in arbitrary locations on the victim's system. This issue
    could also be used in conjunction with a previous race condition
    vulnerability (CAN-2005-1111) to change permissions on files owned by
    the victim.
  
Workaround :

    There is no known workaround at this time."
