シスコシステムズのAdaptive Security Appliance (ASA) Software等の複数製品における範囲外のポインタオフセットの使用に関する脆弱性
Title シスコシステムズのAdaptive Security Appliance (ASA) Software等の複数製品における範囲外のポインタオフセットの使用に関する脆弱性
Summary

Cisco Secure Firewall ASAソフトウェアおよびCisco Secure FTDソフトウェアのOSPFプロトコルに脆弱性が存在します。この脆弱性により、認証されていない隣接する攻撃者がdebug ip ospf canonコマンドを使用し、OSPF正規化デバッグが有効な場合に、影響を受けるデバイスを予期せず再起動させてDoS状態を引き起こす可能性があります。この脆弱性は、OSPF LSUパケットを処理する際の入力検証が不十分であることに起因します。攻撃者は特別に細工された認証されていないOSPFパケットを送信することで、この脆弱性を悪用できます。成功した悪用により、攻撃者はパケットデータ外のメモリに書き込みを行い、デバイスを再起動させてDoS状態を招く可能性があります。

Possible impacts 当該ソフトウェアが扱う情報について、外部への漏えいは発生しません。 また、当該ソフトウェアが扱う情報について、書き換えは発生しません。 さらに、当該ソフトウェアが完全に停止する可能性があります。 そして、この脆弱性を悪用した攻撃の影響は、他のソフトウェアには及びません。
