Artifex: Security Vulnerabilities
psi/zfile.c in Artifex Ghostscript before 9.21rc1 permits the status command even if -dSAFER is used, which might allow remote attackers to determine the existence and size of arbitrary files, a similar issue to CVE-2016-7977.

An exploitable heap out of bounds write vulnerability exists in the Fitz graphical library part of the MuPDF renderer. A specially crafted PDF file can cause a out of bounds write resulting in heap metadata and sensitive process memory corruption leading to potential code execution. Victim needs to open the specially crafted file in a vulnerable reader in order to trigger this vulnerability.

An exploitable memory corruption vulnerability exists in the JBIG2 parser of Artifex MuPDF 1.9. A specially crafted PDF can cause a negative number to be passed to a memset resulting in memory corruption and potential code execution. An attacker can specially craft a PDF and send to the victim to trigger this vulnerability.

ghostscript before version 9.21 is vulnerable to a heap based buffer overflow that was found in the ghostscript jbig2_decode_gray_scale_image function which is used to decode halftone segments in a JBIG2 image. A document (PostScript or PDF) with an embedded, specially crafted, jbig2 image could trigger a segmentation fault in ghostscript.
