SnortにDCE/RPC処理の部分に脆弱性でスタックオーバーフローするそうです。任意のコードをSnort実行権限で実行できるそうです。
Sourcefire has learned of a remotely exploitable vulnerability in the Snort DCE/RPC preprocessor. This preprocessor is vulnerable to a stack-based buffer overflow that could potentially allow attackers to execute code with the same privileges as the Snort binary. Sourcefire has prepared updates for Snort open-source software to address this issue.
