Description John Helmert III gentoo-dev Security 2021-07-22 01:51:31 UTC
CVE-2021-37220:

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.

Unreleased patch: https://git.ghostscript.com/?p=mupdf.git;h=f5712c9949d026e4b891b25837edd2edc166151f
Comment 1 Sam James archtester gentoo-dev Security 2021-07-22 06:15:09 UTC
Asked upstream about versioning given I don't know if 1.18.1 is a proper release or not. Trying to avoid adding just this patch then ending up stabling something else given it likely has security related fixes in it, in short succession.
