This week on the Lock and Code podcast, we speak with EFF public interest technology Cooper Quintin about the hacking tool, the Flipper Zero.

In MicroHttpServer (aka Micro HTTP Server) through 4398570, _ReadStaticFiles in lib/middleware.c allows a stack-based buffer overflow and potentially remote code execution via a long URI.

By Deeba Ahmed The malware, dubbed NKAbuse, uses New Kind of Network (NKN) technology, a blockchain-powered peer-to-peer network protocol to spread its infection. This is a post from HackRead.com Read the original post: New ‘NKAbuse’ Linux Malware Uses Blockchain Technology to Spread

A vulnerability exists on all versions of Ivanti Connect Secure below 22.6R2 where an attacker can send a specific request which may lead to Denial of Service (DoS) of the appliance.

### Impact Versions [v9.26.0](https://github.com/octokit/webhooks.js/releases/tag/v9.26.0), [v10.9.x](https://github.com/octokit/webhooks.js/releases/tag/v10.9.1)), [v11.1.x](https://github.com/octokit/webhooks.js/releases/tag/v11.1.1), [v12.0.x](https://github.com/octokit/webhooks.js/releases/tag/v12.0.3) all contained the code that would throw the error. Specifically, during a pentest we encountered a bug in the octokit/webhooks library (a dependency of Probot, a framework for building Github Apps). The resulting request was found to cause an uncaught exception that ends the nodejs process. The problem is caused by an issue with error handling in the @octokit/webhooks library because the error can be undefined in some cases. Credit goes to @pb82 (for the early analysis) and @rh-tguittet (for discovery). ### Patches Maintenance releases for the Error being thrown by the verify method in [octokit/webhooks.js](https://github.com/octokit/webhooks.js) * v12 - [v12.0.4](https://githu...

octokit/webhooks is a GitHub webhook events toolset for Node.js. Starting in 9.26.0 and prior to 9.26.3, 10.9.2, 11.1.2, and 12.0.4, there is a problem caused by an issue with error handling in the @octokit/webhooks library because the error can be undefined in some cases. The resulting request was found to cause an uncaught exception that ends the nodejs process. The bug is fixed in octokit/webhooks.js 9.26.3, 10.9.2, 11.1.2, and 12.0.4, app.js 14.02, octokit.js 3.1.2, and Protobot 12.3.3.

A denial of service vulnerability exists in all Silicon Labs Z-Wave controller and endpoint devices running Z-Wave SDK v7.20.3 (Gecko SDK v4.3.3) and earlier. This attack can be carried out only by devices on the network sending a stream of packets to the device.

RTPEngine version mr11.5.1.6 suffers from a denial of service vulnerability via DTLS Hello packets during call initiation.

Ubuntu Security Notice 6488-2 - USN-6488-1 fixed a vulnerability in strongSwan. This update provides the corresponding updates for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. Florian Picca discovered that strongSwan incorrectly handled certain DH public values. A remote attacker could use this issue to cause strongSwan to crash, resulting in a denial of service, or possibly execute arbitrary code.

When handling DTLS-SRTP for media setup, Asterisk version 20.1.0 is susceptible to denial of service due to a race condition in the hello handshake phase of the DTLS protocol. This attack can be done continuously, thus denying new DTLS-SRTP encrypted calls during the attack.
