Background ========== polkit is a toolkit for managing policies relating to unprivileged processes communicating with privileged processes. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-print/hplip < 3.14.1 >= 3.14.1 2 net-misc/spice-gtk < 0.21 >= 0.21 3 sys-apps/systemd < 204-r1 >= 204-r1 4 app-emulation/libvirt < 1.1.2-r3 >= 1.1.2-r3 5 sys-auth/polkit < 0.112 >= 0.112 ------------------------------------------------------------------- 5 affected packages Description =========== polkit has a race condition which potentially allows a process to change its UID/EUID via suid or pkexec before authentication is completed. Impact ====== A local attacker could start a suid or pkexec process through a polkit-enabled application, which could result in privilege escalation or bypass of polkit restrictions. Workaround ========== There is no known workaround at this time. Resolution ========== All polkit users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-auth/polkit-0.112" All HPLIP users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-print/hplip-3.14.1" All Spice-Gtk users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/spice-gtk-0.21" All systemd users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/systemd-204-r1" All libvirt users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-emulation/libvirt-1.1.2-r3"= References ========== [ 1 ] CVE-2013-4288 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-4288 [ 2 ] CVE-2013-4311 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-4311 [ 3 ] CVE-2013-4324 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-4324 [ 4 ] CVE-2013-4325 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-4325 [ 5 ] CVE-2013-4327 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-4327 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201406-27.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
