| Descripción: | Summary:
Check the version of kmod-kvm
Vulnerability Insight:
KVM (for Kernel-based Virtual Machine) is
a full virtualization solution for Linux on x86 hardware. Using KVM, one can
run multiple virtual machines running unmodified Linux or Windows images.
Each virtual machine has private virtualized hardware: a network card, disk,
graphics adapter, etc.
Security Fix(es):
* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator
support is vulnerable to an out-of-bounds access issue. It could occur
while copying VGA data via bitblt copy in backward mode. A privileged user
inside a guest could use this flaw to crash the QEMU process resulting in
DoS or potentially execute arbitrary code on the host with privileges of
QEMU process on the host. (CVE-2017-2615)

inside guest could use this flaw to crash the QEMU process OR potentially
execute arbitrary code on host with privileges of the QEMU process.
