A vulnerability has been discovered in the iso.xmd parser that results from a lack of proper validation of user-supplied data, which can result in a division-by-zero circumstance.
Does this matter?
Lower severity and a low EPSS score (0.93%). Track it; it rarely justifies an emergency change on its own.
