Summary

Moderate: virt:rhel and virt-devel:rhel security, bug fix, and enhancement update

Details

Kernel-based Virtual Machine (KVM) 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 (1.3.18), libguestfs (1.40.2), libguestfs-winsupport (8.2), libvirt (6.0.0), libvirt-dbus (1.3.0), libvirt-python (6.0.0), nbdkit (1.16.2), perl-Sys-Virt (6.0.0), qemu-kvm (4.2.0), seabios (1.13.0), SLOF (20191022). (BZ#1810193, BZ#1844296)

Security Fix(es):

libvirt: leak of /dev/mapper/control into QEMU guests (CVE-2020-14339)
QEMU: Slirp: use-after-free during packet reassembly (CVE-2019-15890)
libvirt: Potential DoS by holding a monitor job while querying QEMU guest-agent (CVE-2019-20485)
QEMU: slirp: use-after-free in ip_reass() function in ip_input.c (CVE-2020-1983)
libvirt: Potential denial of service via active pool without target path (CVE-2020-10703)
libvirt: leak of sensitive cookie information via dumpxml (CVE-2020-14301)

CVE-2020-10703 (GCVE-0-2020-10703)

Vulnerability from cvelistv5 – Published: 2020-06-02 00:00 – Updated: 2024-08-04 11:06

Summary

A NULL pointer dereference was found in the libvirt API responsible introduced in upstream version 3.10.0, and fixed in libvirt 6.0.0, for fetching a storage pool based on its target path. In more detail, this flaw affects storage pools created without a target path such as network-based pools like gluster and RBD. Unprivileged users with a read-only connection could abuse this flaw to crash the libvirt daemon, resulting in a potential denial of service.

Severity ?

6.5 (Medium)

CVE-2020-14339 (GCVE-0-2020-14339)

Vulnerability from cvelistv5 – Published: 2020-12-03 00:00 – Updated: 2024-08-04 12:39

Summary

A flaw was found in libvirt, where it leaked a file descriptor for `/dev/mapper/control` into the QEMU process. This file descriptor allows for privileged operations to happen against the device-mapper on the host. This flaw allows a malicious guest user or process to perform operations outside of their standard permissions, potentially causing serious damage to the host operating system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Severity ?

No CVSS data available.
