Descriptions

An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31. The feed_table_tag function in w3m doesn't properly validate the value of table span, which allows remote attackers to cause a denial of service (stack and/or heap buffer overflow) and possibly execute arbitrary code via a crafted HTML page.

Se descubrió un problema en el fork de Tatsuya Kinoshita w3m en versiones anteriores a 0.5.3-31. La función feed_table_tag en w3m no valida adecuadamente el valor span de tabla, lo que permite a atacantes remotos provocar una denegación de servicio (desbordamiento de búfer en memoria dinámica y/o pila) y posiblemente ejecutar código arbitrario a través de una página HTML manipulada.

A large number of security issues were discovered in the w3m browser. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.
