Média
| Vetor | AV:N/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
MIT Kerberos 5 (aka krb5) versions 1.20.2 and earlier, 1.21.x versions prior to 1.21.1
Description
The issue is related to the lib/kadm5/kadm rpc xdr.c file in the Kerberos implementation, where an uninitialized pointer is freed. This can be exploited by a remote authenticated user to trigger a kadmind crash due to the lack of validation between
n key data and the key data array count in the xdr kadm5 principal ent rec function.Recommendations
For MIT Kerberos 5 (aka krb5) versions 1.20.2 and earlier, update to version 1.20.2 or later.
For MIT Kerberos 5 (aka krb5) 1.21.x versions prior to 1.21.1, update to version 1.21.1 or later.
As a temporary workaround, consider restricting access to the vulnerable
lib/kadm5/kadm rpc xdr.c module to minimize the risk of exploitation.Correção

Access of Uninitialized Pointer
