Kernel-based Virtual Machine offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems. The following packages have been upgraded to a later upstream version: hivex , libguestfs , libguestfs-winsupport , libvirt , libvirt-dbus , libvirt-python , nbdkit , perl-Sys-Virt , qemu-kvm , seabios , SLOF . Security Fix: * libvirt: leak of /dev/mapper/control into QEMU guests * QEMU: Slirp: use-after-free during packet reassembly * libvirt: Potential DoS by holding a monitor job while querying QEMU guest-agent * QEMU: slirp: use-after-free in ip_reass function in ip_input.c * libvirt: Potential denial of service via active pool without target path * libvirt: leak of sensitive cookie information via dumpxml For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
