Red Hat Security Advisory 2024-5444-03 - Red Hat OpenShift Container Platform release 4.13.48 is now available with updates to packages and images that fix several bugs and add enhancements. Issues addressed include code execution and memory exhaustion vulnerabilities.

Red Hat Security Advisory 2024-5433-03 - Red Hat OpenShift Container Platform release 4.14.35 is now available with updates to packages and images that fix several bugs and add enhancements. Issues addressed include denial of service and memory exhaustion vulnerabilities.

As cloud infrastructure becomes the backbone of modern enterprises, ensuring the security of these environments is paramount. With AWS (Amazon Web Services) still being the dominant cloud it is important for any security professional to know where to look for signs of compromise. AWS CloudTrail stands out as an essential tool for tracking and logging API activity, providing a comprehensive

One of the key components of a container-based architecture is security.There are many facets to it (just have a look at the list of topics in the official OpenShift documentation here), but some of the most basic requirements are authentication and authorization. In this article, I explain how authentication and authorization work in Kubernetes and Red Hat OpenShift. I cover interactions between the different layers of a Kubernetes ecosystem, including the infrastructure layer, Kubernetes layer, and the containerized applications layer.What is authentication and authorization?In simple terms,

Debian Linux Security Advisory 5750-1 - Support for the "strict kex" SSH extension has been backported to AsyncSSH (a Python implementation of the SSHv2 protocol) as hardening against the Terrapin attack.

Confidential containers are containers deployed within a Trusted Execution Environment (TEE), which allows you to protect your application code and secrets when deployed in untrusted environments. In our previous articles, we introduced the Red Hat OpenShift confidential containers (CoCo) solution and relevant use cases. We demonstrated how components of the CoCo solution, spread across trusted and untrusted environments, including confidential virtual machine (CVM), guest components, TEEs, Confidential compute attestation operator, Trustee agents, and more, work together as part of the soluti

Cybersecurity researchers have discovered a new variant of the Gafgyt botnet that's targeting machines with weak SSH passwords to ultimately mine cryptocurrency on compromised instances using their GPU computational power. This indicates that the "IoT botnet is targeting more robust servers running on cloud native environments," Aqua Security researcher Assaf Morag said in a Wednesday analysis.

### Summary Allocating an untrusted amount of memory allows any unauthenticated user to OOM a russh server. ### Details An SSH packet consists of a 4-byte big-endian length, followed by a byte stream of this length. After parsing and potentially decrypting the 4-byte length, russh allocates enough memory for this bytestream, as a performance optimization to avoid reallocations later. https://github.com/Eugeny/russh/blob/4eaa080e7532662023f75e8fff45b743fe607f8c/russh/src/cipher/mod.rs#L254 But this length is entirely untrusted and can be set to any value by the client, causing this much memory to be allocated, which will cause the process to OOM within a few such requests. RFC 4253 contains an explicit section on packet length limits: https://datatracker.ietf.org/doc/html/rfc4253#section-6.1 > However, implementations SHOULD check that the packet length is reasonable in order for the implementation to avoid denial of service and/or buffer overflow attacks. ### PoC Running the `...
