Title:RHSA-2018:0666: krb5 security, bug fix, and enhancement update (Moderate)
Description:Kerberos is a network authentication system, which can improve the security of your network by eliminating the insecure practice of sending passwords over the network in unencrypted form. It allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos key distribution center (KDC).

Security Fix(es):

  • krb5: Authentication bypass by improper validation of certificate EKU and SAN (CVE-2017-7562)

  • krb5: Invalid S4U2Self or S4U2Proxy request causes assertion failure (CVE-2017-11368)
