"An update for kvm is now available for Red Hat Enterprise Linux 5.
Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
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)
* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA Emulator
support is vulnerable to an out-of-bounds access issue. The issue
could occur while copying VGA data in cirrus_bitblt_cputovideo. A
privileged user inside guest could use this flaw to crash the QEMU
process OR potentially execute arbitrary code on host with privileges
of the QEMU process. (CVE-2017-2620)
Red Hat would like to thank Wjjzhang (Tencent.com Inc.) and Li Qiang
(360.cn Inc.) for reporting CVE-2017-2615."
