Description

This Linux kernel update for SUSE Linux Enterprise 12 fixes the following issues :

  • A previous security update to address CVE-2017-1000364 caused unintended side-effects in several other tools, most notably Java. These issues have been remedied. [bsc#1045340]

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.
