CVE-2013-1416: Fedoraproject Fedora

Medium severity, CVSS 4.0. EPSS: 2.9% chance of exploitation in the next 30 days.

The prep_reprocess_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.5 does not properly perform service-principal realm referral, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted TGS-REQ request.

• Mit Kerberos 5: before 1.10.5 (fixed in 1.10.5)
