"Two vulnerabilities have been discovered in cpio, a program to manage
archives of files. The Common Vulnerabilities and Exposures project
identifies the following problems :

  - CAN-2005-1111
    Imran Ghory discovered a race condition in setting the
    file permissions of files extracted from cpio archives.
    A local attacker with write access to the target
    directory could exploit this to alter the permissions of
    arbitrary files the extracting user has write
    permissions for.

  - CAN-2005-1229

    Imran Ghory discovered that cpio does not sanitise the
    path of extracted files even if the
    --no-absolute-filenames option was specified. This can
    be exploited to install files in arbitrary locations
    where the extracting user has write permissions to."
