CVE-2019-10161 2 Canonical, Redhat 5 Ubuntu Linux, Enterprise Linux, Libvirt and 2 more 2021-03-25 7.2 HIGH 7.8 HIGH
It was discovered that libvirtd before versions 4.10.1 and 5.4.1 would permit read-only clients to use the virDomainSaveImageGetXMLDesc() API, specifying an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause denial of service or cause libvirtd to execute arbitrary programs.
CVE-2020-14339 1 Redhat 2 Enterprise Linux, Libvirt 2021-02-09 7.2 HIGH 8.8 HIGH
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.
CVE-2017-1000256 2 Debian, Redhat 2 Debian Linux, Libvirt 2020-11-16 6.8 MEDIUM 8.1 HIGH
libvirt version 2.3.0 and later is vulnerable to a bad default configuration of "verify-peer=no" passed to QEMU by libvirt resulting in a failure to validate SSL/TLS certificates by default.
CVE-2019-10167 1 Redhat 9 Enterprise Linux, Enterprise Linux Desktop, Enterprise Linux Server and 6 more 2020-10-15 4.6 MEDIUM 7.8 HIGH
The virConnectGetDomainCapabilities() libvirt API, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, accepts an "emulatorbin" argument to specify the program providing emulation for a domain. Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges.
CVE-2018-5748 2 Debian, Redhat 8 Debian Linux, Enterprise Linux Desktop, Enterprise Linux Server and 5 more 2020-10-15 5.0 MEDIUM 7.5 HIGH
qemu/qemu_monitor.c in libvirt allows attackers to cause a denial of service (memory consumption) via a large QEMU reply.
CVE-2019-10168 1 Redhat 9 Enterprise Linux, Enterprise Linux Desktop, Enterprise Linux Server and 6 more 2020-10-15 4.6 MEDIUM 7.8 HIGH
The virConnectBaselineHypervisorCPU() and virConnectCompareHypervisorCPU() libvirt APIs, 4.x.x before 4.10.1 and 5.x.x before 5.4.1, accept an "emulator" argument to specify the program providing emulation for a domain. Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges.
CVE-2019-10166 1 Redhat 9 Enterprise Linux, Enterprise Linux Desktop, Enterprise Linux Server and 6 more 2020-10-15 4.6 MEDIUM 7.8 HIGH
It was discovered that libvirtd, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, would permit readonly clients to use the virDomainManagedSaveDefineXML() API, which would permit them to modify managed save state files. If a managed save had already been created by a privileged user, a local attacker could modify this file such that libvirtd would execute an arbitrary program when the domain was resumed.
CVE-2018-6764 3 Canonical, Debian, Redhat 7 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 4 more 2019-10-03 4.6 MEDIUM 7.8 HIGH
util/virlog.c in libvirt does not properly determine the hostname on LXC container startup, which allows local guest OS users to bypass an intended container protection mechanism and execute arbitrary commands via a crafted NSS module.
CVE-2019-10132 2 Fedoraproject, Redhat 2 Fedora, Libvirt 2019-06-11 6.5 MEDIUM 8.8 HIGH
A vulnerability was found in libvirt >= 4.1.0 in the virtlockd-admin.socket and virtlogd-admin.socket systemd units. A missing SocketMode configuration parameter allows any user on the host to connect using virtlockd-admin-sock or virtlogd-admin-sock and perform administrative tasks against the virtlockd and virtlogd daemons.
CVE-2016-10746 2 Debian, Redhat 2 Debian Linux, Libvirt 2019-05-01 5.0 MEDIUM 7.5 HIGH
libvirt-domain.c in libvirt before 1.3.1 supports virDomainGetTime API calls by guest agents with an RO connection, even though an RW connection was supposed to be required, a different vulnerability than CVE-2019-3886.
CVE-2018-1064 2 Debian, Redhat 2 Debian Linux, Libvirt 2018-06-20 5.0 MEDIUM 7.5 HIGH
libvirt version before 4.2.0-rc1 is vulnerable to a resource exhaustion as a result of an incomplete fix for CVE-2018-5748 that affects QEMU monitor but now also triggered via QEMU guest agent.
