PSA: Serious Security Vulnerability in Tor Browser PSA: Serious Security Vulnerability in Tor Browser ~3 mins | Published by Darknetlive on 25 May, 2022 in News and tagged Tor using 586 words. | 7 Comments HugBunter, who is apparently alive, posted a PSA on Dread about a vulnerability in all FireFox versions < 11.0.13. HugBunter: "Upgrade Tor Browser to the latest release (11.0.13) immediately where possible and ensure you have JavaScript Disabled in Tor Browser at all times, as always. This vulnerability is present in Firefox, and so affects all previous Tor Browser versions < 11.0.13. Affects all platforms, including Tails, as detailed in their warning below. They cannot currently push an emergency release for Tails specifically, will be resolved with a Tor Browser update in Tails 5.1 on May 31."

Update to Tor Browser version 11.0.13 as soon as possible. Tails: Tor Browser in Tails 5.0 and earlier is unsafe to use for sensitive information. We recommend that you stop using Tails until the release of 5.1 (May 31) if you use Tor Browser for sensitive information (passwords, private messages, personal information, etc.). A security vulnerability was discovered in the JavaScript engine of Firefox and Tor Browser. See the Mozilla Foundation Security Advisory 2022-19 This vulnerability allows a malicious website to bypass some of the security built in Tor Browser and access information from other websites. 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. This vulnerability doesn't break the anonymity and encryption of Tor connections. For example, it is still safe and anonymous to access websites from Tails if you don't share sensitive information with them. After Tor Browser has been compromised, the only reliable solution is to restart Tails. Other applications in Tails are not vulnerable. Thunderbird in Tails is not vulnerable because JavaScript is disabled. The Safest security level of Tor Browser is not affected because JavaScript is disabled at this security level. Mozilla is aware of websites exploiting this vulnerability already. 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.

It's all connected. e5f6e824 aaf2b650 Wed, May 25, 2022 what do you mean by LE market 2f07feae 07dcde20 Wed, May 25, 2022 versus was run by LE? wtf are you saying? df503587 d53dd360 Wed, May 25, 2022 was williamgibson actually arrested? link??? im calling bullshit on that until i see proof but it is odd 09428fc4 da709600 Wed, May 25, 2022 not yet probably yesterday c6486b71 523bcb90 Wed, May 25, 2022 what is the key take away lesson from this article like every other time we get a critical CVE related to TOR? never allow javascript you n00bz! if you are on TOR and a website requires javascript consider that website to be a honey pot. MOVE ALONG. 44c6a970 60809e20 Wed, May 25, 2022 These are just the exploits that were disclosed (responsibly) to Mozilla by the pwn2own competition. Nowhere has Mozilla claimed to have evidence of them being exploited in the wild. Not to say that it isn't important to update ASAP, but it seems a bit hyperbolic to make that claim.
