Synopsis ========
A race condition in polkit could allow a local attacker to gain escalated privileges.
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"
