RE : AWS Inspector Shows Critical Updates Pending But Instance Says Otherwise

Question

Hi Team,

Instance ID -  i-0e5934adddc2d8372

I've updated all the packages (See Libcurl-2.png).

But the Inspector still shows critical updates are pending on my instance (See Libcurl-1.png)

Requesting help in investigating this.![![Enter image description here](/media/postImages/original/IMgUGzjYUXQAOinPmO1hAqZg)

>>> This is what Inspector Shows For The Instance :

Affected packages

Installed version / Fixed Version
0:7.79.1-4.amzn2.0.1.X86_64 / 0:7.79.1-6.amzn2.0.1

>>> This is what the Instance shows when trying to remediate (i.e update the package -> It says its already updated)

sh-4.2$ sudo yum update libcurl
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
amzn2-core                                                                                                                                               | 3.7 kB  00:00:00
No packages marked for update
sh-4.2$

Answer

Hey there, There can be a couple of reasons for this.
1. The repositories, yum update is using, to update the pacakges doesn't have latest patches/packages available. 
2. Some of the repositories which could have potential fixes available are in disabled state in your system or your instance doesn't have required access/permissions to connect to the base url of those repos. 
3. Packages to fix these vulnerabilities have not been release yet.
