Descrizione originale
A stack-based buffer overflow vulnerability exists in the SNMP daemon request handling of Brocade Fabric versions before 10.0.1. When processing an incoming SNMPv3 packet, an internal statistics gathering handler copies user-supplied context name data into a fixed-size buffer without properly validating the length of the string. A remote, unauthenticated attacker (under default configuration) can exploit this vulnerability by sending a specially crafted SNMPv3 packet, leading to memory corruption, daemon crash (Denial of Service), or potential arbitrary code execution.
