Synopsis :

The remote openSUSE host is missing a security update.

Description :

The openSUSE 13.2 kernel was updated to fix various bugs and security
issues.

The following security bugs were fixed :

- CVE-2016-1583: Prevent the usage of mmap when the lower
file system does not allow it. This could have lead to
local privilege escalation when ecryptfs-utils was

allowed local users to obtain sensitive information from
kernel memory or possibly have unspecified other impact
via a crafted isofs filesystem (bnc#980725).
