RHSA-2025:2722: Moderate: krb5 security update
First published: Thu Mar 13 2025(Updated: )
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).<br>Security Fix:<br><li> CVE-2025-24528 krb5: overflow when calculating ulog block size</li> Bug fix:<br><li> kdb5_util: fix DB entry flags on modification</li> For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
