CVE-2020-23707
A heap-based buffer overflow vulnerability in the function ok_jpg_decode_block_progressive() at ok_jpg.c:1054 of ok-file-formats through 2020-06-26 allows attackers to cause a Denial of Service (DOS) via a crafted jpeg file.
Does this matter?
Lower severity and a low EPSS score (1.10%). Track it; it rarely justifies an emergency change on its own.
