CVE-2017-8906 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.80% chance of exploitation in the next 30 days.
