Ubuntu Security Notice 6279-1 - It was discovered that OpenSSH has an observable discrepancy leading to an information leak in the algorithm negotiation. This update mitigates the issue by tweaking the client hostkey preference ordering algorithm to prefer the default ordering if the user has a key that matches the best-preference default algorithm.

gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS attacks: - Unbounded memory buffering in the HPACK parser - Unbounded CPU consumption in the HPACK parser The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected by the client. The unbounded memory buffering bugs: - The header size limit check was behind the string reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8 or 16kb. - HPACK varints have an encoding quirk whereby an infinite number of 0’s can be added at the start of an integer. gRPC’s hpack parser needed to read all of them before concluding a parse. - gRPC’s metadata overflow check was performed per frame, so ...

Red Hat Ansible Automation Platform is a platform for implementing enterprise-wide automation, which makes it an ideal tool for your security audits. Security has many layers, but this article focuses on mitigating SSH attacks on managed hosts. While you can't eliminate all security risks, you can harden managed hosts to minimize some of them (especially brute force attacks), and mitigate others (by allowing SSH connections only from authorized hosts, enforcing sudo, and so on). This article uses Ansible Automation Platform, but most of the hardening configuration is applied to the managed hos
