Daniel Stenberg 發現 wget，一個使用 HTTP(S) 與 FTP 從網站取回檔案的網路實用工具，很容易受到「Null Prefix Attacks Against SSL/TLS Certificates」弱點攻擊，這個弱點已在 Blackhat conference 發表了一段時間。這允許攻擊者經由精心製作，在 Common Name 欄位注入空位元組 (null byte) 的 ITU-T X.509 憑證，執行不被注意的中間人攻擊 (man-in-the-middle attacks)。
對於 oldstable distribution (etch)，這個問題已在 1.10.2-2+etch1 版被修正。
對於 stable distribution (lenny)，這個問題已在 1.11.4-2+lenny1 版被修正。
對於 testing distribution (squeeze)，這問題很快會被修正。
對於 unstable distribution (sid)，這個問題已在 1.12-1 版被修正。
我們建議你升級你的 wget 套件。
