MIT Kerberos kadmind RPC Library RPCSEC_GSS Authentication Stack Overflow
Severity: CRITICAL
CVE Identifier: CVE-2007-3999
Advisory Date: FEB 15, 2011
DESCRIPTION
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.
