"This update for gcc43 fixes the following issues: This update adds
support for 'expolines' on s390x, allowing fixing CVE-2017-5715 in a
more lightweight fashion. (bsc#1086069) The option flags are the same
as for the x86 retpolines. A compiler crash when building userland
packages with x86 retpolines was fixed. (bsc#1092807)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
