EulerOS Virtualization 2.5.2 : kernel (EulerOS-SA-2018-1407)

medium Nessus Plugin ID 119896

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 :

 - An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking.
 This is similar to CVE-2018-10940.(CVE-2018-16658)

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.
