CVE-2013-4291
The virSecurityManagerSetProcessLabel function in libvirt 0.10.2.7, 1.0.5.5, and 1.1.1, when the domain has read an uid:gid label, does not properly set group memberships, which allows local users to gain privileges.
Does this matter?
Lower severity and a low EPSS score (0.49%). Track it; it rarely justifies an emergency change on its own.
