Affected Products:
openSUSE Leap 42.2
______________________________________________________________________________
An update that solves one vulnerability and has 27 fixes is
now available.
Description:
The openSUSE Leap 42.2 kernel was updated to 4.4.73 to receive security
and bugfixes.
The following security bugs were fixed:
– CVE-2017-1000364: An issue was discovered in the size of the stack guard
page on Linux, specifically a 4k stack guard page is not sufficiently
large and can be “jumped” over (the stack guard page is bypassed), this
affects Linux Kernel versions 4.11.5 and earlier (the stackguard page
was introduced in 2010) (bnc#1039348).
The previous fix caused some Java applications to crash and has been
replaced by the upstream fix.
