NVD Description

Note: Versions mentioned in the description apply only to the upstream mupdf package and not the mupdf package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

MuPDF through 1.18.1 has an out-of-bounds write because the cached color converter does not properly consider the maximum key size of a hash table. This can, for example, be seen with crafted "mutool draw" input.
