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

  - A format string flaw exists in the Vim help tag
    processor in the helptags_one() function that allows a
    remote attacker to execute arbitrary code by tricking a
    user into executing the 'helptags' command on malicious
    help files. (CVE-2007-2953)

  - Multiple flaws exist in the Vim system functions due to
    a failure to sanitize user-supplied input. An attacker
    can exploit these to execute arbitrary code by tricking
    a user into opening a crafted file. (CVE-2008-2712)

  - A heap-based buffer overflow condition exists in the Vim
    mch_expand_wildcards() function. An attacker can exploit
    this, via shell metacharacters in a crafted file name,
    to execute arbitrary code. (CVE-2008-3432)

  - Multiple flaws exist in Vim keyword and tag handling due
    to improper handling of escape characters. An attacker
    can exploit this, via a crafted document, to execute
    arbitrary shell commands or Ex commands. (CVE-2008-4101)

  - A security bypass vulnerability exists in OpenSSL due to
    a failure to properly check the return value from the
    EVP_VerifyFinal() function. A remote attacker can
    exploit this, via a malformed SSL/TLS signature for DSA
    and ECDSA keys, to bypass the validation of the
    certificate chain. (CVE-2008-5077)

  - A security bypass vulnerability exists in BIND due to a
    failure to properly check the return value from the
    OpenSSL DSA_verify() function. A remote attacker can
    exploit this, via a malformed SSL/TLS signature, to
    bypass the validation of the certificate chain on those
    systems using DNSSEC. (CVE-2009-0025)");
