Descriptions

An issue was discovered in wifipcap/wifipcap.cpp in TCPFLOW through 1.5.0-alpha. There is an integer overflow in the function handle_prism during caplen processing. If the caplen is less than 144, one can cause an integer overflow in the function handle_80211, which will result in an out-of-bounds read and may allow access to sensitive memory (or a denial of service).

Se ha descubierto un problema en wifipcap/wifipcap.cpp en TCPFLOW hasta la versión 1.5.0-alpha. Hay un desbordamiento de enteros en la función handle_prism durante el procesamiento de caplen. Si el caplen es menor que 144, se puede provocar un desbordamiento de enteros en la función handle_80211, lo que resultará en una lectura fuera de límites y podría permitir el acceso a memoria sensible (o una denegación de servicio).
