    Package        : ganeti
    Vulnerability  : missing input sanitation
    Problem type   : local (remote)
    Debian-specific: no
    CVE Id(s)      : CVE-2009-4261
    
    It was discovered that ganeti, a virtual server cluster manager, does
    not validate the path of scripts passed as arguments to certain
    commands, which allows local or remote users (via the web interface in
    versions 2.x) to execute arbitrary commands on a host acting as a
    cluster master.
    
    For the stable distribution (lenny), this problem has been fixed in
    version 1.2.6-3+lenny2.
    
    For the testing distribution (squeeze), this problem will be fixed
    in version 2.0.5-1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.0.5-1.
    
    The oldstable distribution (etch) does not include ganeti.
    
    
    We recommend that you upgrade your ganeti packages.
