Descriptions
In nbd-server in nbd before 3.24, there is a stack-based buffer overflow. An attacker can cause a buffer overflow in the parsing of the name field by sending a crafted NBD_OPT_INFO or NBD_OPT_GO message with an large value as the length of the name.
En nbd-server en nbd versiones anteriores a 3.24, se presenta un desbordamiento del búfer en la región stack de la memoria. Un atacante puede causar un desbordamiento de búfer en el análisis del campo name enviando un mensaje NBD_OPT_INFO o NBD_OPT_GO diseñado con un valor grande como longitud del nombre
Shannon Baseband suffers from a memory corruption vulnerability that occurs when the baseband modem processes SDP when setting up a call. When an fmtp attribute is parsed, the integer that represents the payload type is copied into an 8-byte buffer using memcpy with the length of payload type as the length parameter. There are no checks that the payload type is less than 8-bytes long or actually an integer.
