Description

This security bulletin contains information about 1 vulnerability.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-4401)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote #AU# to execute arbitrary code.

The virConnectDomainXMLToNative API function in libvirt 1.1.0 through 1.1.3 checks for the connect:read permission instead of the connect:write permission, which allows attackers to gain domain:write privileges and execute Qemu binaries via crafted XML. NOTE: some of these details are obtained from third party information.


Remediation

Install update from vendor's website.
