In some cases, use of this library could introduce out-of-bounds writes that are not present in an application's source code.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
