EulerOS 2.0 SP1 : qemu-kvm (EulerOS-SA-2017-1118)

high Nessus Plugin ID 101850

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the qemu-kvm package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data using bitblt functions (for example, cirrus_bitblt_rop_fwd_transp_). A privileged user inside a guest could use this flaw to crash the QEMU process, resulting in denial of service.
 (CVE-2017-7718)

 - An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2017-7980)

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 packages.
