Description
This security bulletin contains information about 1 vulnerability.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-4291)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: 8.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local non-authenticated attacker to execute arbitrary code.
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.
