Mozilla Thunderbird < 68.4.1

high Nessus Plugin ID 132773

概要

遠端 macOS 或 Mac OS X 主機上安裝的電子郵件用戶端受到多個弱點影響。

說明

遠端 macOS 或 Mac OS X 主機上安裝的 Thunderbird 版本比 68.4.1 版舊。因此會受到 mfsa2020-04 公告中所提及的多個弱點影響。- 貼上時 <style> tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly rewrites a @namespace rule. This could allow for injection into certain types of websites resulting in data exfiltration. This vulnerability affects Thunderbird < 68.4. (CVE-2019-17016) - Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.4. (CVE-2019-17017) - When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not escape < and > characters. Because the resulting string is pasted directly into the text node of the element this does not result in a direct injection into the webpage; however, if a webpage subsequently copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability. Two WYSIWYG editors were identified with this behavior, more may exist. This vulnerability affects Thunderbird < 68.4. (CVE-2019-17022) Mozilla developers Jason Kratzer, Christian Holler, and Bob Clary reported memory safety bugs present in Thunderbird 68.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. (CVE-2019-17024) - Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type confusion. We are aware of targeted attacks in the wild abusing this flaw. (CVE-2019-17026) Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

解決方案

升級至 Mozilla Thunderbird 68.4.1 版或更新版本。
