SUSE SLED15 / SLES15 Security Update : kernel (SUSE-SU-2018:2223-1)

medium Nessus Plugin ID 120071

Language:

Synopsis

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

Description

The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes. The following security bugs were fixed:
CVE-2018-5390 aka SegmentSmack: A remote attacker even with relatively low bandwidth could have caused lots of CPU usage by triggering the worst case scenario during IP and/or TCP fragment reassembly (bsc#1102340)

- CVE-2017-18344: The timer_create syscall implementation didn't properly validate input, which could have lead to out-of-bounds access. This allowed userspace applications to read arbitrary kernel memory in some setups. (bsc#1102851)

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.
