CVE-2014-9665

Estado: ModificadaAlta (7.5)—

La función Load_SBit_Png en sfnt/pngshim.c en FreeType anterior a 2.5.4 no restringe los valores de filas y tonos de los datos PNG, lo que permite a atacantes remotos causar una denegación de servicio (desbordamiento de enteros y desbordamiento de buffer basado en memoria dinámica) o posiblemente tener otro impacto no especificado mediante el embebido de un fichero PNG en un fichero de fuentes .ttf.
