Description Florian Weimer 2013-11-19 13:52:46 UTC 
IPC_PRIVATE is a misnomer, and this will create a SHM segment with 0777 permissions:

  tex_pixmap->shm_info.shmid = shmget (IPC_PRIVATE,
                                       dummy_image->bytes_per_line
                                       * dummy_image->height,
                                       IPC_CREAT | 0777);

This should probably use 0600 permissions instead.  As far as I can see, it's a cosmetic issue because the SHM segment is only temporary and not used for anything important.
