CVE-2019-6133

Priority
Description
In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can
be bypassed because fork() is not atomic, and therefore authorization
decisions are improperly cached. This is related to lack of uid checking in
polkitbackend/polkitbackendinteractiveauthority.c.
Ubuntu-Description
Jann Horn discovered a race condition in the fork() system call in the
Linux kernel. A local attacker could use this to gain access to services
that cache authorizations.
Notes
 mdeslaur> This issue is better fixed in the kernel, adding kernel
 mdeslaur> packages to this CVE.
