SUSE Linux Enterprise Server 12-SP5
______________________________________________________________________________
An update that solves 13 vulnerabilities and has 28 fixes
is now available.
Description:
The SUSE Linux Enterprise 12 SP5 Azure kernel was updated to receive
various security and bugfixes.
