According to our vulnerability management system we need to update our ESXi 4.1U1 servers to the latest version.
I checked the patch security articles and there are just a couple of vulnerabilities that are reported by vmware.
There are not so much information which feature of the software is affected by this security hole, so I cannot decide if it is needed or not.
I had a lot of problems in the past with the installation of the updates mainly with windows server and I am very suspicous when I have to update anything.
Our ESXi server(management network) are on different network segment and connection to them are allowed only from IT department network. Virtualization software that we are using also are vcenter and srm(site recovery manager).
Could you tell me if this updates are so requered and critical, do you update constantly your vmware servers, or any advice maybe.
The most reported seems to be
•The ESX/ESXi userworld libxml2 library is updated to resolve multiple security issues
-The userworld glibc third-party library is updated to 2.5-58.el5_6.2 resolve multiple security issues
•629880: This release resolves an integer overflow issue in the SFCB that arises when the httpMaxContentLength is changed from its default value to 0 in /etc/sfcb/sfcb.cfg. The integer overflow could allow remote attackers to cause a denial of service (heap memory corruption) or possibly execute arbitrary code via a large integer in the Content-Length HTTP header
