______________________________________________________________________________
An update that solves two vulnerabilities and has one
errata is now available.
Description:
This update for the Linux Kernel 3.12.62-60_62 fixes several issues.
The following security bugs were fixed:
- CVE-2016-5195: A local privilege escalation using MAP_PRIVATE was fixed,
which is reportedly exploited in the wild (bsc#1004419).
- CVE-2016-8666: The IP stack in the Linux kernel allowed remote attackers
to cause a denial of service (stack consumption and panic) or possibly
have unspecified other impact by triggering use of the GRO path for
packets with tunnel stacking, as demonstrated by interleaved IPv4
headers and GRE headers, a related issue to CVE-2016-7039 (bsc#1001486).
