Tails 是一个专注于安全的便携式 Linux 发行版，最近，它的开发团队发布了有关其当前版本的重要公告。他们警告用户在 **Tails 5.0 或更早版本** 上使用 Tor 浏览器时，避免输入或使用任何个人或敏感信息。


Tor 浏览器是 Tails 事实上的（默认）网页浏览器，它有助于在用户连接到互联网时，保护他们的在线身份。它主要被各种记者和活动家用来逃避审查。不过，普通用户也可以使用它。


### 问题说明


最近，有人发现了两个令人讨厌的漏洞，它们允许有害网站能够从其他网站窃取用户的信息。


这些都是在 Firefox 使用的 JavaScript 引擎中发现的。


但是，Tor 与此有什么关系？对于那些不知道的人来说，Tor 实际上是 Firefox 的一个复刻，因此包含许多类似的功能，如 JavaScript 引擎。


具体来说，在 [Mozilla 发布的公告](https://www.mozilla.org/en-US/security/advisories/mfsa2022-19/) 中，这些漏洞已被确定为 CVE-2022-1802 和 CVE-2022-1529。


Tails 公告中也对此进行了说明：



> 
> “例如，在你访问恶意网站后，控制该网站的攻击者可能会在同一个 Tails 会话期间，访问你随后发送到其他网站的密码或其他敏感信息。”
> 
> 
> 


### 你应该停止使用 Tail 发行版吗？


没有这个必要。


用户会很高兴地知道，这些漏洞并不影响 Tor 的连接。这意味着，如果你不交换任何敏感信息，如密码、个人信息、信息等，你可以随意地浏览互联网。


Tails 中的其他应用程序，尤其是 Thunderbird，仍然可以安全使用，因为 JavaScript 在使用时会被禁用。


此外，你也可以在 Tor 浏览器中启用最高的安全级别。这是推荐的，因为（该级别下）JavaScript 引擎会被禁用。不过，请注意，这会使网站无法正常运行。


换句话说，如果你知道自己在做什么的话，Tails 发行版仍然可以安全使用。


### 漏洞修复即将发布


好的消息是，Mozilla 已经在上游修补了这些错误，现在就等 Tails 团队发布修复程序了。


至于何时发布，他们是这样说的：



> 
> 此漏洞将在 Tails 5.1（**5 月 31 日**）中修复，但我们的团队没有能力提前发布紧急版本。
> 
> 
> 


因此，你最好的选择是等待下周的 Tails 5.1 发布。你可以阅读 Tails 开发团队的 [官方公告](https://tails.boum.org/security/prototype_pollution/index.en.html) 以了解更多信息。

The developers of the security-focused portable Linux distro, **Tails**, have recently released an important advisory regarding its current release. They have warned users to avoid entering or using any personal or sensitive information while using Tor Browser on **Tails 5.0 or older**.

Tor Browser is the de-facto web browser used in Tails and helps protect the user’s identity online when connected to the Internet. It is mainly used by various journalists and activists to evade censorship. Everyday users can use it too.

## What’s the problem?

Recently, two nasty vulnerabilities have been found that enable harmful websites to steal the user’s information from other websites.

These had been discovered in the JavaScript engine used by Firefox.

But what has Tor to do with this? For those unaware, Tor is actually a fork of Firefox and thus contains many similar features like the JavaScript engine.

To be specific, the vulnerabilities have been identified as CVE-2022-1802 and CVE-2022-1529 in an [advisory published by Mozilla.](https://www.mozilla.org/en-US/security/advisories/mfsa2022-19/?ref=news.itsfoss.com)

The Tails advisory best explains this:

“For example, after you visit a malicious website, an attacker controlling this website might access the password or other sensitive information that you send to other websites afterwards during the same Tails session.”


## Should You Stop Using Tails Linux Distro?

Not necessarily.

Users will be glad to know that these vulnerabilities don’t affect Tor connections. This means you can casually browse the internet if you’re not exchanging any of your sensitive information like passwords, personal information, messages, etc.

Other apps in Tails, especially Thunderbird, are safe to use since the JavaScript is disabled if in use.

Furthermore, you can even enable the safest security level in the Tor browser. This is preferred because the JavaScript engine gets disabled. Do note that this will make websites function improperly.

In other words, the Tails Linux distro is still safe to use if you know what you’re doing.

## A Fix is Coming Soon

Good news! Mozilla has already patched these bugs upstream and now it’s up to the Tails team when it comes to releasing the fix.

Here’s what they have stated –

This vulnerability will be fixed in Tails 5.1 (

May 31), but our team doesn’t have the capacity to publish an emergency release earlier.

So, your best option is to wait for the Tails 5.1 release next week. You can read the [official advisory](https://tails.boum.org/security/prototype_pollution/index.en.html?ref=news.itsfoss.com) released by Tails devs to know more.
