| Description: | The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed.
Security Fix(es):
It was discovered that the ghostscript /invalidaccess checks fail under certain conditions. An attacker could possibly exploit this to bypass the -dSAFER protection and, for example, execute arbitrary shell commands via a specially crafted PostScript document. (CVE-2018-16509)
ghostscript: LockDistillerParams type confusion (699656) (CVE-2018-15910)
ghostscript: .definemodifiedfont memory corruption if /typecheck is handled (699668) (CVE-2018-16542)
ghostscript: Stack-based out-of-bounds write in pdf_set_text_matrix function in gdevpdts.c (CVE-2018-10194)
