产品: Kylin V3
发布日期: 2019年6月20日
CVE: CVE-2019-10161
CVSS3评分: 8.8
概述:
* This vulnerability requires access to the libvirt socket, normally in /var/run/libvirt/libvirt_sock_ro. Typically in hypervisor environments, local user accounts are not supported so no untrusted users should be able to access this socket. * Kylin Gluster Storage 3 is not affected by this vulnerability as libvirtd daemon is not shipped in Gluster. * On Kylin Enterprise Linux 6, the impact of this vulnerability is limited to denial of service or disclosing the existence of arbitrary files. Privilege escalation is not possible. For Kylin6, this CVE is rated as Moderate severity with 7.3/CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:H 描述:
** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided. 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. 系统版本:
