The build_principal_va function in lib/krb5/krb/bld_princ.c in MIT Kerberos 5 (aka krb5) before 1.14 allows remote authenticated users to cause a denial of service (out-of-bounds read and KDC crash) via an initial '\0' character in a long realm field within a TGS request.

Security readout for executives and security teams

This flaw can let a logged-in Kerberos user crash a vulnerable MIT Kerberos KDC. The business risk is authentication disruption: affected services may fail because Kerberos tickets cannot be issued. The source bundle does not show public active exploitation or a CVSS score. Exposure is most likely on systems running MIT Kerberos 5 KDC components before 1.14, including older vendor-packaged krb5 deployments referenced by Debian, Ubuntu, SUSE, Gentoo, and Oracle advisories. Treat this as a moderate availability risk. Prioritize patching any production KDCs because Kerberos outages can interrupt authentication-dependent business services, even though the bundle shows authenticated access is required. Mitigation focus: Upgrade MIT Kerberos 5 to 1.14 or later where applicable.; Apply the fixed krb5 packages from your operating system vendor.; Review Debian, Ubuntu, SUSE, Gentoo, and Oracle advisories for platform-specific guidance..
