CVE-2008-3825

Estado: ModificadaMedia (4.4)—

pam_krb5 2.2.14 de Red Hat Enterprise Linux (RHEL) 5 y versiones anteriores, cuando la opción existing_ticket está activa, utiliza privilegios incorrectos cuando lee una caché de credenciales Kerberos, lo cual permite a usuarios locales conseguir privilegios mediante el establecimiento de la variable de entorno KRB5CCNAME en un nombre de fichero cacheado de su elección y ejecutar los programas (1) su o (2) sudo. NOTA: puede haber un vector relacionado con la participación de sshd que tiene una importancia limitada.
