Linux admins -

Understanding the threats we face as Linux security admins means that we can better safeguard our data, educate stakeholders more effectively, and build trust among everyone involved. Having a fundamental understanding of an out-of-bounds write flaw as one of those more complex threats we should be aware of and how it can be used to allow attackers to execute arbitrary code on our servers is essential.

Read on to learn more about this flaw and how it can be exploited for malicious activities to escalate into a major security incident.

The Discovery 

An out-of-bounds write vulnerability occurs when a program writes data outside the bounds of allocated memory. 

LinuxKernel Esm W206

The Impact

These dangerous flaws can result in system compromise, denial of service, privilege escalation, and chained attacks.

The Fix

Linux distros frequently release patch updates for the latest out-of-bounds write flaws. Admins should apply these patches immediately and make sure they have upgraded and updated their Linux distro to the latest version to protect against exploits. 

F5 BIG-IP

The Discovery 

A severe, actively exploited BIG-IP privilege escalation flaw that impacts many enterprises and government networks has been discovered.

Server Security Esm W400

The Impact

This vulnerability gives attackers a way around authentication and enables remote code execution on the control plane, granting system-level access, complete visibility into traffic management, and encrypted session handling.

The Fix

Patches have been released to mitigate this critical bug. All impacted admins and organizations should apply these patches immediately to secure their networks and systems against privilege escalation attacks.
