简介

远程 Windows 主机上安装的邮件客户端受到多个漏洞的影响。

描述

远程 Windows 主机上安装的 Thunderbird 版本低于 68.4.1。因此,如公告 mfsa2020-04 所述,受到多个漏洞的影响。- 在初始化新内容进程期间,指针偏移可被操控,从而导致父进程中内存损坏以及潜在可利用的崩溃。*请注意:此问题仅出现在 Windows 中。其他操作系统不受影响。* 此漏洞影响 Thunderbird < 68.4。(CVE-2019-17015) - 当粘贴 <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) - During the initialization of a new content process, a race condition occurs that can allow a content process to disclose heap addresses from the parent process. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 68.4. (CVE-2019-17021) - 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.

解决方案

升级版本到 Mozilla Thunderbird 68.4.1 或更高版本。
