Medium
| Vector | AV:A/AC:H/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
libvirt versions prior to 1.2.9
libvirt-client version 0.10.2
libvirt-devel version 0.10.2
libvirt-debuginfo version 0.10.2
libvirt-python version 0.10.2
Description
The issue affects the confidentiality, integrity, and availability of protected information. It is related to the
virDomainListPopulate function in conf/domain conf.c, which does not clean up the lock on the list of domains. This allows remote attackers to cause a denial of service (deadlock) via a NULL value in the second parameter in the virConnectListAllDomains API command.Recommendations
For libvirt versions prior to 1.2.9, update to version 1.2.9 or later to resolve the issue.
For libvirt-client version 0.10.2, consider disabling the
virConnectListAllDomains API command until a patch is available.
For libvirt-devel version 0.10.2, restrict access to the conf/domain conf.c module to minimize the risk of exploitation.
For libvirt-debuginfo version 0.10.2, avoid using the virDomainListPopulate function until the issue is resolved.
For libvirt-python version 0.10.2, consider disabling the virConnectListAllDomains API command until a patch is available.Fix
