Description Dr. Werner Fink 2016-02-22 11:49:32 UTC 
It seems that there is no secure way to open a shared meory object in a secure way using the offcial POSIX shared memory API of the glibc as described in man:shm_overview(7).  This was already reported on other places, e.g.

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=620887

and also got implemented for openBSD:
