OpenID
這幾天在寫 OpenID 的 server (以交大裡的三套郵件系統為認證基礎:D2、Faculty、Mail),讀 OpenID Authentication 1.1 規格書發現 spec 寫的好與壞對於規格的推動有很大的差異 -_- OpenID 的規格書是屬於超難懂的那種,第一個原因是裡面用了不少關於密碼學的理論或是實做 (HMAC、SHA-1、Diffie-Hellman key exchange),第二個原因是很多細節的地方缺乏具體的定義,如果不直接看其他人已經寫出來的 source code,讀起來很辛苦… @_@ 不管怎麼樣,希望這幾天寫一寫,到時候就可以利用 OpenID 跑很多東西…
在 WordPress.com 上用 LaTeX 數學式
在 WordPress.com 的 Blog 上看到 WordPress.com 上可以用 LaTeX 數學式了:Math for the Masses。 用 Google 找了一下發現有人寫出來了:Using LaTeX in WordPress,雖然我自己用不到,不過對於拿 WordPress 來放數學題目的人倒是蠻有用,像是這個:93學年度清華大學數學系應數組碩士班考試高等微積分第五題。
Google Summer of Code 2007
Slashdot 上看到 Google Summer of Code 2007 開放報名了,如同往年,Google 讓許多 Open Source Community 提出 project,由 Google 買單:Google Launches Summer of Code 2007。

在 mozilla links 上看到 Firefox 2.0.0.1 因為對 DOM 的處理不當造成 Cookie 外漏以及其他的安全漏洞:New Firefox cookie vulnerability, workaround,Bug Report 在 Bugzilla@Mozilla 的 Zalewski cookie setting / same-domain bypass vulnerability。 按照 Bug Report 上的說明,問題在於 location.hostname 這個變數上。惡意的站台可以故意將 location.hostname 設為 ‘evil.com\x00foo.example.com’,於是真正在連 hostname 時會因為 C-style string 而只判讀到 … Continue reading
µTorrent 1.6.1

趨勢防毒軟體的安全漏洞
趨勢防毒軟體的安全漏洞:Another Anti-Virus Problem,趨勢官方的安全通告在這裡:Antivirus UPX Parsing Kernel Buffer Overflow Vulnerability,因為 UPX buffer overflow 而產生的安全問題。 剛剛查 Wikipedia 上的資料才知道 Trend Micro 總部設在日本…

幾個安全漏洞…
兩個安全漏洞: Sun Solaris 10 與 11 的 Telnet 有安全漏洞,可以讓外面的人直接拿到 root:Solaris Telnet 0-day vulnerability。 µTorrent 1.6 安全漏洞,看 source code 是從 torrent 檔下手:This is a PoC remote exploit for uTorrent 1.6,這幾天應該就會有新版了。
