| Description: | Summary:
The remote host is missing an update for the 'kernel, kernel-userspace-headers, kmod-vboxadditions, kmod-virtualbox, kmod-xtables-addons' package(s) announced via the MGASA-2016-0401 advisory.
Vulnerability Insight:
This update is based on upstream 4.4.32 and fixes at least the following
security issues:
The proc_keys_show function in security/keys/proc.c in the Linux kernel
through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is
enabled, uses an incorrect buffer size for certain timeout data, which
allows local users to cause a denial of service (stack memory corruption
and panic) by reading the /proc/keys file (CVE-2016-7042).
Null pointer dereference in kvm/emulate.c (CVE-2016-8630).
A buffer overflow vulnerability due to a lack of input filtering of
incoming fragmented datagrams was found in the IP-over-1394 driver
[firewire-net] in a fragment handling code in the Linux kernel. A
maliciously formed fragment with a respectively large datagram offset
would cause a memcpy() past the datagram buffer, which would cause a
system panic or possible arbitrary code execution. The flaw requires
[firewire-net] module to be loaded and is remotely exploitable from
connected firewire devices, but not over a local network (CVE-2016-8633).
For other fixes in this update, see the referenced changelogs.
Affected Software/OS:
'kernel, kernel-userspace-headers, kmod-vboxadditions, kmod-virtualbox, kmod-xtables-addons' package(s) on Mageia 5.
Solution:
Please install the updated package(s).
