Synopsis

遠端 macOS 或 Mac OS X 主機上安裝的網頁瀏覽器受到多個弱點影響。

描述

遠端 macOS 或 Mac OS X 主機上安裝的 Firefox ESR 版本比 68.4 舊。因此,會受到 mfsa2020-02 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. (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. (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. (CVE-2019-17022) - Mozilla developers Jason Kratzer, Christian Holler, and Bob Clary reported memory safety bugs present in Firefox 71 and Firefox ESR 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) 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
