    Package        : xfsdump
    Vulnerability  : insecure file creation
    Problem-Type   : local
    Debian-specific: no
    CVE Id         : CAN-2003-0173
    Ethan Benson discovered a problem in xfsdump, that contains
    administrative utilities for the XFS filesystem.  When filesystem
    quotas are enabled xfsdump runs xfsdq to save the quota information
    into a file at the root of the filesystem being dumped.  The manner in
    which this file is created is unsafe.
    While fixing this, a new option ``-f path'' has been added to xfsdq(8)
    to specify an output file instead of using the standard output stream.
    This file is created by xfsdq and xfsdq will fail to run if it exists
    already.  The file is also created with a more appropriate mode than
    whatever the umask happened to be when xfsdump(8) was run.
    For the stable distribution (woody) this problem has been fixed in
    version 2.0.1-2.
    The old stable distribution (potato) is not affected since it doesn't
    contain xfsdump packages.
    For the unstable distribution (sid) this problem has been fixed in
    version 2.2.8-1.
    We recommend that you upgrade your lpr package immediately.
