ghostscript: Segmentation fault in the xps_true_callback_glyph_name function

The xps_true_callback_glyph_name function in xps/xpsttf.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (Segmentation Violation and application crash) via a crafted file.

ghostscript: Buffer overflow in the xps_load_sfnt_name function

The xps_load_sfnt_name function in xps/xpsfont.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted document.

ghostscript: Use-after-free in the Ins_IP function

The Ins_IP function in base/ttinterp.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly have unspecified other impact via a crafted document.

ghostscript: Divide-by-zero in the intersect function

The intersect function in base/gxfill.c in Artifex Software, Inc. Ghostscript 9.20 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted file.

ghostscript: Heap-buffer over-read in the Ins_MIRP function

The Ins_MIRP function in base/ttinterp.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document.

ghostscript: Heap-buffer over-read in the xps_load_sfnt_name function

The xps_load_sfnt_name function in xps/xpsfont.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document.

The pdf_to_num function in pdf-object.c in MuPDF before 1.10 allows remote attackers to cause a denial of service (use-after-free and application crash) via a crafted file.

jbig2dec: Null pointer dereference in jbig2_huffman_get()

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.
