An issue was discovered in Artifex Ghostscript before 10.03.1. psi/zmisc1.c, when SAFER mode is used, allows eexec seeds other than the Type 1 standard.
Artifex Ghostscript before 9.53.0 has an out-of-bounds write and use-after-free in devices/vector/gdevtxtw.c (for txtwrite) because a single character code in a PDF document can map to more than one Unicode code point (e.g., for a ligature).
A floating point exception (divide-by-zero) vulnerability was discovered in Artifex MuPDF 1.23.4 in the function fz_new_pixmap_from_float_data() of pixmap.c.
A floating point exception (divide-by-zero) vulnerability was discovered in Artifex MuPDF 1.23.4 in function pnm_binary_read_image() of load-pnm.c when span equals zero.
A floating point exception (divide-by-zero) vulnerability was discovered in mupdf 1.23.4 in function pnm_binary_read_image() of load-pnm.c when fz_colorspace_n returns zero.
A floating point exception (divide-by-zero) vulnerability was discovered in Artifex MuPDF 1.23.4 in functon compute_color() of jquant2.c. NOTE: this is disputed by the supplier because there was not reasonable evidence to determine the existence of a vulnerability or identify the affected product.
