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

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


Synopsis :

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

Description :

* A buffer overflow flaw was found in the way the qeth_snmp_command()
function in the Linux kernel's QETH network device driver
implementation handled SNMP IOCTL requests with an out-of-bounds
length. A local, unprivileged user could use this flaw to crash the
system or, potentially, escalate their privileges on the system.
(CVE-2013-6381, Important)

* A flaw was found in the way the get_dumpable() function return value
was interpreted in the ptrace subsystem of the Linux kernel. When
'fs.suid_dumpable' was set to 2, a local, unprivileged local user
could use this flaw to bypass intended ptrace restrictions and obtain
potentially sensitive information. (CVE-2013-2929, Low)

* It was found that certain protocol handlers in the Linux kernel's
networking implementation could set the addr_len value without
initializing the associated data structure. A local, unprivileged user
could use this flaw to leak kernel stack memory to user space using
the recvmsg, recvfrom, and recvmmsg system calls (CVE-2013-7263,
CVE-2013-7265, Low).

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