Artifex: Security Vulnerabilities
The gs_alloc_ref_array function in psi/ialloc.c in Artifex Ghostscript 9.21 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document. This is related to a lack of an integer overflow check in base/gsalloc.c.

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.

Artifex jbig2dec 0.13 allows out-of-bounds writes and reads because of an integer overflow in the jbig2_image_compose function in jbig2_image.c during operations on a crafted .jb2 file, leading to a denial of service (application crash) or disclosure of sensitive information from process memory.
