EulerOS Virtualization 2.5.2 : kernel (EulerOS-SA-2018-1352)

High Nessus Plugin ID 118440

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the version of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

- A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a denial of service on the system.(CVE-2018-5391)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected kernel package.
