This update for ghostscript-library fixes the following issues:

• 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, bsc#1001951)

• An incorrect reference count was found in .setdevice. This issue lead to a use-after-free scenario, which could have been exploited for denial-of-service or, possibly, arbitrary code execution attacks. (CVE-2016-7978, bsc#1001951)

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