Descriptions

The svcauth_gss_accept_sec_context function in lib/rpc/svc_auth_gss.c in MIT Kerberos 5 (aka krb5) 1.11.x through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 transmits uninitialized interposer data to clients, which allows remote attackers to obtain sensitive information from process heap memory by sniffing the network for data in a handle field.

La función svcauth_gss_accept_sec_context en lib/rpc/svc_auth_gss.c en MIT Kerberos 5 (también conocido como krb5) 1.11.x hasta 1.11.5, 1.12.x hasta 1.12.2, y 1.13.x anterior a 1.13.1 trasmite datos intercalados no inicializados a clientes, lo que permite a atacantes remotos obtener información sensible de la memoria dinámica de procesos mediante la captura de trafico de la red para datos en un campo de manejo (handle).

An information disclosure flaw was found in the way MIT Kerberos RPCSEC_GSS implementation (libgssrpc) handled certain requests. An attacker could send a specially crafted request to an application using libgssrpc to disclose a limited portion of uninitialized memory used by that application.
