Description

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, 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)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
