1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-4400)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

virt-login-shell in libvirt 1.1.2 through 1.1.3 allows local users to overwrite arbitrary files and possibly gain privileges via unspecified environment variables or command-line arguments.


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

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.
