medium Nessus Plugin ID 119060
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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 :

- The timer_create syscall implementation in kernel/time/posix-timers.c in the Linux kernel doesn't properly validate the sigevent-i1/4zsigev_notify field, which leads to out-of-bounds access in the show_timer function.(CVE-2017-18344)

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.
