CVE-2020-0452
In exif_entry_get_value of exif-entry.c, there is a possible out of bounds write due to an integer overflow.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
