Blob Blame History Raw

Subject: [PATCH] ccpp: include the system logs only with root's coredumps

Search for suspicious lines in 'journalctl' only if uid == 0.  A problem
of the type CCpp can be created only by root so no user can trick abrt
to run 'post-create' on a malicious problem directory with uid == 0.
