EulerOS Virtualization for ARM 64 3.0.2.0 : libvirt (EulerOS-SA-2019-1957)
high Nessus Plugin ID 128960
Synopsis
The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.Description
According to the versions of the libvirt packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :- It was discovered that libvirtd 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-2019-10161)
- The virConnectGetDomainCapabilities() libvirt API 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-2019-10167)
- The virConnectBaselineHypervisorCPU() and virConnectCompareHypervisorCPU() libvirt APIs 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-2019-10168)
