CVE-2015-3228: Integer Overflow
First published: Wed Jun 17 2015(Updated: )
Integer overflow in the gs_heap_alloc_bytes function in base/gsmalloc.c in Ghostscript 9.15 and earlier allows remote attackers to cause a denial of service (crash) via a crafted Postscript (ps) file, as demonstrated by using the ps2pdf command, which triggers an out-of-bounds read or write.
