CentOS Errata and Security Advisory CESA-2018:2918
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)
