An updated rhev-hypervisor5 package that fixes multiple security
issues and various bugs is now available.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
The rhev-hypervisor5 package provides a Red Hat Enterprise
Virtualization Hypervisor ISO disk image. The Red Hat Enterprise
Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine
(KVM) hypervisor. It includes everything necessary to run and manage
virtual machines: A subset of the Red Hat Enterprise Linux operating
environment and the Red Hat Enterprise Virtualization Agent.
Note: Red Hat Enterprise Virtualization Hypervisor is only available
for the Intel 64 and AMD64 architectures with virtualization
A flaw was found in the way QEMU handled VT100 terminal escape
sequences when emulating certain character devices. A guest user with
privileges to write to a character device that is emulated on the host
using a virtual console back-end could use this flaw to crash the
qemu-kvm process on the host or, possibly, escalate their privileges
on the host. (CVE-2012-3515)
Multiple integer overflow flaws, leading to stack-based buffer
overflows, were found in glibc's functions for converting a string to
a numeric representation (strtod(), strtof(), and strtold()). If an
application used such a function on attacker controlled input, it
could cause the application to crash or, potentially, execute
arbitrary code. (CVE-2012-3480)
Red Hat would like to thank the Xen project for reporting the
This updated package provides updated components that include various

however, for this component, it had no security impact on Red Hat
Enterprise Virtualization Hypervisor itself.
Users of Red Hat Enterprise Virtualization Hypervisor are advised to
upgrade to this updated package, which fixes these issues.
