CVE-ID : CVE-2021-3560
Package : polkit
Type : privilege escalation
Remote : No
Link : https://security.archlinux.org/AVG-2028
The package polkit before version 0.119-1 is vulnerable to privilege
escalation.
Upgrade to 0.119-1.
The problem has been fixed upstream in version 0.119.
None.
A security issue was found in polkit before version 0.119. When a
requesting process disconnects from dbus-daemon just before the call to
polkit_system_bus_name_get_creds_sync starts, the process cannot get a
unique uid and pid of the process and it cannot verify the privileges
of the requesting process.
A local attacker could escalate privileges by exploiting a race
condition.
