4 | Subject: [PATCH] Ensure a device has raster memory, before trying to read it. | ||
5 | |||
6 | Bug #697676 "Null pointer dereference in mem_get_bits_rectangle()" | ||
7 | |||
8 | This is only possible by abusing/mis-using Ghostscript-specific | ||
9 | language extensions, so cannot happen in a general PostScript program. | ||
10 | |||
11 | Nevertheless, Ghostscript should not crash. So this commit checks the | ||
12 | memory device to see if raster memory has been allocated, before trying | ||
13 | to read from it. | ||
