A vulnerability has been identified in Sourcefire Intrusion Sensor and Snort, which could be exploited by attackers to cause a denial of service or execute arbitrary commands. This issue is due to a buffer overflow error within the DCE/RPC preprocessor (enabled by default) when processing malformed data via the "ReassembleSMBWriteX()" and "ReassembleDCERPCRequest()" functions, which could be exploited by attackers to compromise a vulnerable system by sending specially crafted packets to a network being monitored by a vulnerable application.
