GHSA-6WFW-M2Q3-X7RQ

Vulnerability from github – Published: 2022-05-14 03:07 – Updated: 2022-05-14 03:07

Details

An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The pre-defined function "strlen" is getting a "NULL" string as a parameter value in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the Key Distribution Center (KDC), which allows remote authenticated users to cause a denial of service (NULL pointer dereference) via a modified kadmin client.

Severity ?

6.5 (Medium)


                  
                    CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
