Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200710-01
(RPCSEC_GSS library: Buffer overflow)

A stack based buffer overflow has been discovered in the
svcauth_gss_validate() function in file lib/rpc/svc_auth_gss.c when
processing an overly long string in a RPC message.

Impact :

A remote attacker could send a specially crafted RPC request to an
application relying on this library, e.g NFSv4 or Kerberos
(GLSA-200709-01), resulting in the execution of arbitrary code with the
privileges of the user running the application.

Workaround :

There is no known workaround at this time.
