DESCRIPTION:
VMware has acknowledged a security issue and some vulnerabilities in
VMware vMA, which can be exploited by malicious people to disclose
potentially sensitive information, cause a DoS (Denial of Service) or
potentially compromise a vulnerable system.

1) Some vulnerabilities are caused due to integer underflows within
the AES and RC4 decryption when handling ciphertexts shorter than the
minimum expected length.

For more information:
SA38080

2) The security issue is caused due to pam_krb5 returning different
password prompts depending on whether or not a valid user name is
supplied

For more information:
SA35230

SOLUTION:
Restrict access to trusted users only. Filter network access using a
firewall. Restrict access to the pam_krb5 password prompt.
