Vulnerabilidad de elevación de privilegios en Kerberos RC4-HMAC de Windows
An update that fixes three vulnerabilities is now available. This update for samba fixes the following issues. Fixed an issue where the bad password count would not be properly incremented, which could allow attackers to brute force a user's password. Disabled weak ciphers by default in the Netlogon Secure channel. Fixed an issue where a weak cipher would be selected to encrypt session keys, which could lead to privilege escalation.
