CVE-2022-3378
If a user opens a maliciously formed FNT file, then an attacker could execute arbitrary code within the current process by accessing an uninitialized pointer, leading to an out-of-bounds memory write.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
