Wireshark の IEEE 802.11 ディセクタの epan/dissectors/packet-ieee80211.c におけるサービス運用妨害 (DoS) の脆弱性

Title	Wireshark の IEEE 802.11 ディセクタの epan/dissectors/packet-ieee80211.c におけるサービス運用妨害 (DoS) の脆弱性
Summary	Wireshark の IEEE 802.11 ディセクタの epan/dissectors/packet-ieee80211.c 内の (1) dissect_tfs_request および (2) dissect_tfs_response 関数は、ゼロ値をエラーの状態ではなく長さとして解釈するため、サービス運用妨害 (無限ループ) 状態にされる脆弱性が存在します。
Possible impacts	第三者により、巧妙に細工されたパケットを介して、サービス運用妨害 (無限ループ) 状態にされる可能性があります。
Solution	ベンダより正式な対策が公開されています。ベンダ情報を参照して適切な対策を実施してください。

NVD Vulnerability Information

CVE-2015-3814

Summary	The (1) dissect_tfs_request and (2) dissect_tfs_response functions in epan/dissectors/packet-ieee80211.c in the IEEE 802.11 dissector in Wireshark 1.10.x before 1.10.14 and 1.12.x before 1.12.5 interpret a zero value as a length rather than an error condition, which allows remote attackers to cause a denial of service (infinite loop) via a crafted packet.
