Description

According to the versions of the libvirt packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • libvirt: arbitrary file read/exec via virDomainSaveImageGetXMLDesc API (CVE-2019-10161)

  • libvirt: virDomainManagedSaveDefineXML API exposed to readonly clients (CVE-2019-10166)

  • libvirt: arbitrary command execution via virConnectGetDomainCapabilities API (CVE-2019-10167)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
