Categoría:	Huawei EulerOS Local Security Checks
Título:	Huawei EulerOS: Security Advisory for libvirt (EulerOS-SA-2019-1957)
Resumen:	The remote host is missing an update for the Huawei EulerOS 'libvirt' package(s) announced via the EulerOS-SA-2019-1957 advisory.
Descripción:	Summary: The remote host is missing an update for the Huawei EulerOS 'libvirt' package(s) announced via the EulerOS-SA-2019-1957 advisory. Vulnerability Insight: 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) Affected Software/OS: 'libvirt' package(s) on Huawei EulerOS Virtualization for ARM 64 3.0.2.0. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
