Stack-based buffer overflow in the svcauth_gss_validate function in lib/rpc/svc_auth_gss.c in the RPCSEC_GSS RPC library (librpcsecgss) in MIT Kerberos 5 (krb5) 1.4 through 1.6.2, as used by the Kerberos administration daemon (kadmind) and some third-party applications that use krb5, allows remote attackers to cause a denial of service (daemon crash) and probably execute arbitrary code via a long string in an RPC message.

Security readout for executives and security teams

This is an old but serious Kerberos-related memory corruption issue. A specially long value in an RPC message can crash affected Kerberos administration services and may allow code execution. Business risk is highest where legacy MIT Kerberos 5 versions or applications using librpcsecgss remain exposed to untrusted networks. Exposure is likely limited to legacy systems running MIT Kerberos 5 1.4 through 1.6.2 or applications linked to affected RPCSEC_GSS code. Internet or broad internal exposure of kadmind or related RPC services increases urgency. Treat as high priority for legacy identity infrastructure. This affects Kerberos administration paths, where service crashes or possible code execution can disrupt authentication operations and increase compromise impact. Mitigation focus: Identify systems running MIT krb5 1.4 through 1.6.2 or affected vendor packages.; Check OS vendor advisories for the exact fixed krb5 or librpcsecgss packages.; Prioritize upgrades for exposed kadmind and RPCSEC_GSS-dependent services..
