CVE-2019-3572

Estado: ModificadaMedia (6.5)—

Se ha descubierto un problema en libming 0.4.8. Hay una sobrelectura de búfer basada en memoria dinámica (heap) en la función writePNG en el archivo util/dbl2png.c del programa de línea de comandos "dbl2png". Debido a que esto se asocia con una llamada errónea a png_write_row en libpng, podría ocurrir una lectura fuera de límites para algunos diseños de memoria.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
