An even closer study of the certificate used by iPCU revealed that it only contains Signature in key usage. via cryptopath.wordpress.com - VeriSignが出した証明書は「/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=www.verisign.com/repository/RPA Incorp. by Ref.,LIAB.LTD(c)98/OU=Persona Not Validated/OU= ...

iPhoneで、http proxyとtrust anchor設定をいじるmobileconfig fileの更新が、iPhoneのデフォルトのtrusted storeからたどれる、KUにdigitalSignatureが入ってる証明書で署名したものなら、いかにもgreenっぽい画面出して書き換えられる、という話のようです。 > @kjur

うーむ、Posterousに切られると困るな: VeriSignが出した証明書は「/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=www.verisign.com/repository/RPA Incorp. by Ref.,LIAB.LTD(c)98/OU=Persona Not Validated/OU=Digital ID Class 1 - Netscape/CN=Apple Computer/emailAddress=apple.iphone.updates@gmail.com」とはいえ確かにVeriSignにどうこうできる話じゃない。MacOS Xに、Windowsのcertificate propertyみたいな分類がなければ、EVとかかなあ。

I like the way the writer chose to portray this as an iPhone vulnerability rather than a "Verisign screwing up it's job as a CA"

The Cryptopath blog, which unveiled the flaw, stated, "VeriSign is not to blame for this in any way."
- Allen L. Kelly
Good point - the summary implied that this was closer to the infamous mistake with a Microsoft code signing certificate. I'm still a bit leery of the no-review test certificates but Apple definitely should have restricted this feature further than a simple "Signed by any root CA" check.

Turkiyede temsilcisi olan bi tane sec. cok detayli bakmadim ama Verisign bu is icin iyi gorunuyor. Para konusunda Comodo sanirim en uygunu. Ve onlar da iyidir.
