CVE-2010-4478

Summary	OpenSSH 5.6 and earlier, when J-PAKE is enabled, does not properly validate the public parameters in the J-PAKE protocol, which allows remote attackers to bypass the need for knowledge of the shared secret, and successfully authenticate, by sending crafted values in each round of the protocol, a related issue to CVE-2010-4252.

OpenSSH における共有秘密鍵の認証要求を回避される脆弱性

Title	OpenSSH における共有秘密鍵の認証要求を回避される脆弱性
Summary	OpenSSH は、J-PAKE が有効な際、J-PAKE プロトコル内のパブリックパラメータを適切に検証しないため、共有秘密鍵の認証要求を回避される脆弱性が存在します。本問題は、CVE-2010-4252 と関連する問題です。
Possible impacts	第三者により、巧妙に細工された値をプロトコルの各ラウンド内に送信されることにより、認証を突破され、共有秘密鍵の認証要求を回避される可能性があります。
Solution	ベンダ情報及び参考情報を参照して適切な対策を実施してください。
