Descriptions

A global buffer overflow in OptiPNG 0.7.6 allows remote attackers to cause a denial-of-service attack or other unspecified impact with a maliciously crafted GIF format file, related to an uncontrolled loop in the LZWReadByte function of the gifread.c file.

Un desbordamiento de búfer global en OptiPNG 0.7.6 permite que atacantes remotos provoquen un ataque de denegación de servicio (DoS) u otro impacto sin especificar con un archivo maliciosamente manipulado de formato GIF. Esto se relaciona con un bucle no controlado en la función LZWReadByte del archivo gifread.c.

Two vulnerabilities were discovered in optipng, an advanced PNG optimizer, which may result in denial of service or the execution of arbitrary code if a malformed file is processed.
