- 存在多重八位元編碼問題，可導致跨網站指令碼攻擊，而多位元組字元集中的某些八位元可能會損毀下列八位元。
 (CVE-2012-0471)

- 使用「cairo-dwrite」轉譯字型時存在一個錯誤，可造成記憶體損毀，進而導致當機，以及可能的程式碼執行。(CVE-2012-0472)

遠端主機受到 GLSA-201301-01 中所述的弱點影響 (Mozilla 產品：多個弱點)

在 Mozilla Firefox、Thunderbird、SeaMonkey、NSS、GNU IceCat 與 XULRunner 中發現多個弱點。如需詳細資訊，請檢閱以下提及的 CVE 識別碼。
 影響：

遠端攻擊者可引誘使用者檢視特製的網頁或電子郵件，進而可能導致執行任意程式碼或拒絕服務情況。此外，遠端攻擊者或許能夠執行攔截式攻擊、取得敏感資訊、繞過限制及保護機制、強制檔案下載、發動 XML 插入攻擊、發動 XSS 攻擊、繞過同源原則、偽造 URL 以發動網路釣魚攻擊、觸發垂直捲動、偽造位置列、偽造 SSL 指示器、修改瀏覽器的字型、發動點擊劫持攻擊，或造成其他不明的影響。
 本機攻擊者可取得提升的權限、取得敏感資訊，或取代任意下載檔案。

目前尚無已知的因應措施。

Versions of Mozilla Thunderbird prior to 12.0 are affected by the following security issues :

 - An error exists with handling JavaScript errors that could lead to information disclosure. (CVE-2011-1187)
 - An off-by-one error exists in the 'OpenType Sanitizer' that could lead to out-bounds-reads and possible code execution. (CVE-2011-3062)
 - Memory safety issues exist that could lead to arbitrary code execution. (CVE-2012-0467, CVE-2012-0468)
