Does this matter?
Lower severity and a low EPSS score (1.33%). Track it; it rarely justifies an emergency change on its own.
Description
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.
