Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

- CVE-2018-1087: And an unprivileged KVM guest user could use this flaw to potentially escalate their privileges inside a guest. (bsc#1087088)

- CVE-2018-8897: An unprivileged system user could use incorrect set up interrupt stacks to crash the Linux kernel resulting in DoS issue. (bsc#1087088)

- CVE-2018-10124: The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN argument (bnc#1089752).

The update package also includes non-security fixes. See advisory for details.

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.
