NVD Description

Note: Versions mentioned in the description apply only to the upstream krb5 package and not the krb5 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

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.
