Red Hat Security Advisory 2015-0439-01

Posted Mar 5, 2015

Red Hat Security Advisory 2015-0439-01 - A NULL pointer dereference flaw was found in the MIT Kerberos SPNEGO acceptor for continuation tokens. A remote, unauthenticated attacker could use this flaw to crash a GSSAPI-enabled server application. A buffer overflow was found in the KADM5 administration server when it was used with an LDAP back end for the KDC database. A remote, authenticated attacker could potentially use this flaw to execute arbitrary code on the system running kadmind. A use-after-free flaw was found in the way the MIT Kerberos libgssapi_krb5 library processed valid context deletion tokens. An attacker able to make an application using the GSS-API library call the gss_process_context_token() function could use this flaw to crash that application.
