Scientific Linux Security Update : kernel on SL6.x i386/x86_64

This script is Copyright (C) 2014-2015 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

* It was found that the Linux kernel's ptrace subsystem allowed a
traced process' instruction pointer to be set to a non-canonical
memory address without forcing the non-sysret code path when returning
to user space. A local, unprivileged user could use this flaw to crash
the system or, potentially, escalate their privileges on the system.
(CVE-2014-4699, Important)

Note: The CVE-2014-4699 issue only affected systems using an Intel
CPU.

* A flaw was found in the way the pppol2tp_setsockopt() and
pppol2tp_getsockopt() functions in the Linux kernel's PPP over L2TP
implementation handled requests with a non-SOL_PPPOL2TP socket option
level. A local, unprivileged user could use this flaw to escalate
their privileges on the system. (CVE-2014-4943, Important)

The system must be rebooted for this update to take effect.
