Shellshock–Related Attacks Continue
A new Shellshock attack targeting SMTP servers was discovered by Trend Micro. Attackers used email to deliver the exploit. If the exploit code is executed successfully on a vulnerable SMTP server, an IRC bot known as “JST Perl IrcBot” will be downloaded and executed. It will then delete itself after execution, most likely as a way to go under the radar and remain undetected. The diagram below ill
ShellShockの衝撃 -- バグの舞台裏
原文(投稿日：2014/09/29)へのリンク 現在悪名高い、例のbashのバグCVE-2014-6271 は、後に「ShellShock」として知られるようになった。このバグはコードのリモート実行を許可してしまうもので、直接的または間接的にbashスクリプトを実行しているサーバに対し、巧妙に作成されたデータをネットワーク越しに送信することで起こる。最初のバグは修正されたが、後続の、解析ルーチンに関するゼロデイの懸念は2つ目の脆弱性CVE-2014-7169をもたらした。こちらの脆弱性は公開されてから週末にかけて修正された。しかし、この脆弱性はなぜ起こったのだろうか。また、この手のバグはこれが最後となるのだろうか。FreeBSDやNetBSDは、関数を自動的にインポートする機能をデフォルトで無効にした。将来の脆弱性を防ぐためだ。 問題が発生する理由は、Bashシェルにとある機能（ バグでは
DNSを悪用して脆弱性「Shellshock」を攻撃する手法発見 - Full Disclosure
bashのセキュリティ脆弱性(通称:Shellshock)の影響はいまだとどまることなく、さらに広がりを見せている。この脆弱性を攻撃する手法としてすでにHTTPやDHCPが知られているが、新たにDNSの逆引きを利用する方法が発見された。さまざまなメディアで報道されているが、例えばFull Disclosureに掲載された「Full Disclosure: CVE-2014-3671: DNS Reverse Lookup as a vector for the Bash vulnerability (CVE-2014-6271 et.al.)」などが興味深い。スレッドで、この問題について詳しく解説されている。 DNSの逆引きの結果として「() { :;}; echo CVE-2014-6271, CVE-201407169, RDNS」といったShellshockを悪用する文字列を返すよう

Vulnerability POC testing with ServerSpec · Sam Kottler
Every once in a while there's a vulnerabiilty to core components of the systems we rely on every day. Recently there was the "shellshock" vulnerability in bash, which potentially allows remote code execution. At DigitalOcean, we have many, many machines and use Chef to manage all of them. As we got ready to deploy the bash update to our fleet, wfarr and I were talking about what our ServerSpec tes
CVE-2014-6271 fix for Debian woody, sarge, etch and lenny
Very old Debian releases like woody (3.0), sarge (3.1), etch (4.0) and lenny (5.0) are not supported anymore by the Debian Security Team and do not get security updates. Since some of our customers still have servers running these version, I have built bash packages with the fix for CVE-2014-6271 (the "shellshock" bug) and Florian Weimer's patch which restricts the parsing of shell functions to sp
