RHBA-2023:3731 - krb5 bug fix update
Synopsis
krb5 bug fix update
Type/Severity
Bug Fix Advisory None
Topic
An update for krb5 is now available for Red Hat Enterprise Linux 9.
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).
Bug Fix(es):
-
PKINIT module initialization fails if a well-known MODP group cannot be loaded (BZ#2209715)
-
PKINIT: CMS SHA-1 signature verification cannot be allowed in FIPS mode (BZ#2209717)
-
Make ticket signature optional during PAC verification (BZ#2211388)
Solution
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing the updated packages, running Kerberos services (krb5kdc, kadmin, and kprop) will be restarted automatically.
