Does this matter?
Lower severity and a low EPSS score (0.80%). Track it; it rarely justifies an emergency change on its own.
Description
An integer underflow vulnerability exists in pixel-a.asm, the x86 assembly code for planeClipAndMax() in MulticoreWare x265 through 2.4, as used by the x265_encoder_encode dependency in libbpg and other products. A small picture can cause an integer underflow, which leads to a Denial of Service in the process of encoding.
