Critical vulnerability has been fixed upstream, but Tails dev team ‘doesn’t have the capacity to publish an emergency release earlier’

A walkthrough of one of the stealthy communication techniques employed in a recent attack using APT34's Saitama backdoor. The post How the Saitama backdoor uses DNS tunnelling appeared first on Malwarebytes Labs.

If one word could sum up the 2021 infosecurity year (well, actually three), it would be these: "supply chain attack".  A software supply chain attack happens when hackers manipulate the code in third-party software components to compromise the 'downstream' applications that use them. In 2021, we have seen a dramatic rise in such attacks: high profile security incidents like the SolarWinds,

radareorg radare2 version 5.5.2 is vulnerable to NULL Pointer Dereference via libr/bin/p/bin_symbols.c binary symbol parser.

Google has issued an update for the Chrome browser to patch 32 security issues . One of the vulnerabilities is rated as critical, so install that update as soon as you can. The post Update now! Multiple vulnerabilities patched in Google Chrome appeared first on Malwarebytes Labs.

Popular video conferencing service Zoom has resolved as many as four security vulnerabilities, which could be exploited to compromise another user over chat by sending specially crafted Extensible Messaging and Presence Protocol (XMPP) messages and execute malicious code. Tracked from CVE-2022-22784 through CVE-2022-22787, the issues range between 5.9 and 8.1 in severity. Ivan Fratric of Google

### Impact _What kind of vulnerability is it? Who is impacted?_ Disclosed by Aapo Oksman (Senior Security Specialist, Nixu Corporation). > PyJWT supports multiple different JWT signing algorithms. With JWT, an > attacker submitting the JWT token can choose the used signing algorithm. > > The PyJWT library requires that the application chooses what algorithms > are supported. The application can specify > "jwt.algorithms.get_default_algorithms()" to get support for all > algorithms. They can also specify a single one of them (which is the > usual use case if calling jwt.decode directly. However, if calling > jwt.decode in a helper function, all algorithms might be enabled.) > > For example, if the user chooses "none" algorithm and the JWT checker > supports that, there will be no signature checking. This is a common > security issue with some JWT implementations. > > PyJWT combats this by requiring that the if the "none" algorithm is > used, the key has to be empty. As the...

### Impact The [macros that TensorFlow uses for writing assertions (e.g., `CHECK_LT`, `CHECK_GT`, etc.)](https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/platform/default/logging.h) have an incorrect logic when comparing `size_t` and `int` values. Due to type conversion rules, several of the macros would trigger incorrectly. ### Patches We have patched the issue in GitHub commit [b917181c29b50cb83399ba41f4d938dc369109a1](https://github.com/tensorflow/tensorflow/commit/b917181c29b50cb83399ba41f4d938dc369109a1) (merging GitHub PR [#55730](https://github.com/tensorflow/tensorflow/pull/55730)). The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range. ### For more information Please consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more informati...

A flaw was found in Wildfly. An incorrect JBOSS_LOCAL_USER challenge location when using the elytron configuration may lead to JBOSS_LOCAL_USER access to all users on the machine. The highest threat from this vulnerability is to confidentiality, integrity, and availability. This flaw affects wildfly-core versions prior to 17.0.

New features include context-aware, zero-trust data protection on local peripherals and devices.
