"The remote VMware ESX host is missing a security-related patch. It is,
therefore, affected by multiple vulnerabilities :

  - A flaw exists in sudo in file parse.c due to a failure
    to properly interpret a system group (%group) in the
    sudoers configuration file when handling authorization
    decisions for users belonging to that group. A local
    attacker can exploit this to gain root privileges via a
    crafted sudo command. (CVE-2009-0034)

  - A flaw exists in the redirect implementation in libcurl
    that allows arbitrary Location values to be accepted
    when CURLOPT_FOLLOWLOCATION is enabled. An attacker
    with control of a remote HTTP server can exploit this,
    via crafted redirect URLs, to trigger requests to
    intranet servers, to read or write arbitrary files, or
    to execute arbitrary commands. (CVE-2009-0037)

  - A flaw exists in udev due to a failure to verify that a
    NETLINK message originates from the kernel space. A
    local attacker can exploit this, via a crafted NETLINK
    message, to gain elevated privileges on the root file
    system. (CVE-2009-1185)");
