                              SGI Security Advisory
    
    Title    : xfsdump creates files insecurely
    Number   : 20030404-01-P
    Date     : April 10, 2003
    Reference: CVE CAN-2003-0173
    Reference: SGI BUG 885222
    Fixed in : IRIX 6.5.20 (when available) or patches 5059 and 5060
    ______________________________________________________________________________
    
    - -----------------------
    - --- Issue Specifics ---
    - -----------------------
    
    It's been reported that xfsdump creates quota information files insecurely,
    possibly leading to a root exploit by a local user.
    
    See: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0173
    
    SGI has investigated the issue and recommends the following steps for
    neutralizing the exposure.  It is HIGHLY RECOMMENDED that these measures be
    implemented on ALL vulnerable SGI systems.
    
    These issues have been corrected with patches and in future releases of
    IRIX.
    
    
    - --------------
    - --- Impact ---
    - --------------
    
    The xfsdump binary is installed by default on IRIX 6.5 systems as part of
    eoe.sw.base.
    
    To determine the version of IRIX you are running, execute the following
    command:
    
      # /bin/uname -R
    
    That will return a result similar to the following:
    
      # 6.5 6.5.16f
    
    The first number ("6.5") is the release name, the second ("6.5.16f" in this
    case) is the extended release name.  The extended release name is the
    "version" we refer to throughout this document.
    
    
    - ----------------------------
    - --- Temporary Workaround ---
    - ----------------------------
    
    There is no effective workaround available for these problems if you need to
    use xfsdump on xfs filesystems with quotas.  SGI recommends either upgrading
    to IRIX 6.5.20 (when available), or installing the appropriate patch from
    the listing below.
    
    
    - ----------------
    - --- Solution ---
    - ----------------
    
    SGI has provided a series of patches for these vulnerabilities. Our
    recommendation is to upgrade to IRIX 6.5.20 (when available), or install the
    appropriate patch.
