- Multiple security vulnerabilities have been discovered where ghostscript's
 '-dsafer' flag did not provide sufficient protection against unintended
 access to the file system. Thus, a machine that would process a specially
 crafted Postscript file would potentially leak sensitive information to an
 attacker. (CVE-2013-5653, CVE-2016-7977, bsc#1001951)

- Insufficient validation of the type of input in .initialize_dsc_parser used
 to allow remote code execution. (CVE-2016-7979, bsc#1001951)

- An integer overflow in the gs_heap_alloc_bytes function used to allow remote
 attackers to cause a denial of service (crash) via specially crafted
 Postscript files. (CVE-2015-3228, boo#939342)");
