error from cron job on cliupdate.php concerning libpng

It is a bug in older versions of libpng according to https://bugzilla.redhat.com/show_bug.cgi?id=1121035

I found this too. The bug was closed because of insufficient data.
What is really irritating that the error message does not appear on every run of the cronjob.
Is it possible that during the cronjob the shared host runs out of memory and then the error occurs?

Also I have a new behaviour:
The error is now changing from the original error to a new one:
libpng warning: iCCP: known incorrect sRGB profile

Sometimes both errors occur at the same time, most of the times they are alternating
