Summary
krb5 vulnerability
Details

It was discovered that Kerberos allowed the usage of weak cryptographic standards. An attacker could possibly use this issue to expose sensitive information.

This update introduces the allowrc4 and allowdes3 configuration options, and disables the usage of RC4 and 3DES ciphers by default. Users are advised to discontinue their usage and upgrade to stronger encryption protocols. If the use of the insecure RC4 and 3DES algorithms is necessary, they can be enabled with the aforementioned configuration options.
