Name of the Vulnerable Software and Affected Versions MIT Kerberos 5 versions prior to 1.14

Description The issue allows remote authenticated users to cause a denial of service, resulting in an out-of-bounds read and KDC crash. This can be achieved by including an initial '0' character in a long realm field within a TGS request.

Recommendations For versions prior to 1.14, update to version 1.14 or later to resolve the issue. As a temporary workaround, consider restricting access to the build principal va function in lib/krb5/krb/bld princ.c to minimize the risk of exploitation.
