New! Plugin Severity Now Using CVSS v3

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

- The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.(CVE-2018-7550)

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 qemu-kvm package.
