November 7, 2022 Doug Bidwell

Hello good people of IBM i Land. There’s a security vulnerability you need to take a look at to see if it affects your system, and a whole bunch of PTF patches for all kinds of things. Let’s start with the vulnerability, which you can see in Security Bulletin: Zlib for IBM i is vulnerable to a buffer overflow issue during inflate (CVE-2022-37434) and which you can find out more about here.

This is not the same vulnerability in Zlib for IBM i that we told you about last week, so don’t think we are a skipping record here.
