IDs

RLSA-2023:1141, CVE-2023-0361

Description

We tried to scan one of our container images and realized one of the CVE is not getting reported.

Reproduction Steps

1/
A normal OS scan is triggered:
> trivy image --scanners vuln --vuln-type os --format json <IMAGE> --output ~/Downloads/vout.json

2/
The following commands didn't output anything
- cat ~/Downloads/vout.json | grep CVE-2023-0361
- cat ~/Downloads/vout.json | grep RLSA-2023:1141

3/ Retriggering OS scan and listing all the packages on the same image:
> trivy image --scanners vuln --vuln-type os --format json <IMAGE> --output ~/Downloads/vout.json --list-all-pkgs

4/ Find gnutls library in the output and we can see that version `[email protected]_0.x86_64` is installed.

{
          "ID": "[email protected]_0.x86_64",
          "Name": "gnutls",
          "Version": "3.7.6",
          "Release": "12.el9_0",
          "Arch": "x86_64",
          "SrcName": "gnutls",
          "SrcVersion": "3.7.6",
          "SrcRelease": "12.el9_0",
          "Licenses": [
            "GPLv3+ and LGPLv2+"
          ],
          "Maintainer": "Rocky Enterprise Software Foundation",
          "DependsOn": [
            "[email protected]",
            "[email protected]_64",
            "[email protected]_64",
            "[email protected]_64",
            "[email protected]_64",
            "[email protected]_0.x86_64",
            "[email protected]_64",
            "[email protected]_64"
          ],
          "Layer": {
            "Digest": "sha256:5d7e16de9e63c217694b078d1c99f462e513de81f01ab8a3111e378128e83420",
            "DiffID": "sha256:a480c1f046c8ccdd2cb4ec5e4fc8583a4a34a1f40b9176ee294bc4203c9124ce"
          },
          "Digest": "md5:f794d86ae8c2a7857472aa5313cce683"
},


5/ Based on RLSA-2023:1141 / https://errata.rockylinux.org/RLSA-2023:1141
The fixed version is gnutls-0:3.7.6-18.el9_1
The expected behavior of the scanner would be flagging the installed library `[email protected]_0.x86_64` and ask the update to a newer version.
