ghostscript: CVE-2016-7977, CVE-2016-7978, CVE-2016-7979, CVE-2017-9216
Ghostscript before 9.21 might allow remote attackers to bypass the SAFER
mode protection mechanism and consequently read arbitrary files via the
use of the .libfile operator in a crafted postscript document.
Use-after-free vulnerability in Ghostscript 9.20 might allow remote
attackers to execute arbitrary code via vectors related to a reference
leak in .setdevice.
Ghostscript before 9.21 might allow remote attackers to bypass the SAFER
mode protection mechanism and consequently execute arbitrary code by
leveraging type confusion in .initialize_dsc_parser.
libjbig2dec.a in Artifex jbig2dec 0.13, as used in MuPDF and Ghostscript,
has a NULL pointer dereference in the jbig2_huffman_get function in
jbig2_huffman.c. For example, the jbig2dec utility will
crash (segmentation fault) when parsing an invalid file.
