Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1751 advisory.

- vim is vulnerable to Use After Free (CVE-2022-0156)

- vim is vulnerable to Heap-based Buffer Overflow (CVE-2022-0158, CVE-2022-0213)

- Heap-based Buffer Overflow in GitHub repository vim/vim prior to 8.2. (CVE-2022-0261, CVE-2022-0359)

- Heap-based Buffer Overflow in vim/vim prior to 8.2. (CVE-2022-0318)

- Access of Memory Location Before Start of Buffer in GitHub repository vim/vim prior to 8.2. (CVE-2022-0351)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update vim' to update your system.

How to Run


Here is how to run the Amazon Linux 2 : vim (ALAS-2022-1751) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

  1. Click to start a New Scan.
  2. Select Advanced Scan.
  3. Navigate to the Plugins tab.
  4. On the top right corner click to Disable All plugins.
  5. On the left side table select Amazon Linux Local Security Checks plugin family.
  6. On the right side table select Amazon Linux 2 : vim (ALAS-2022-1751) plugin ID 158211.
  7. Specify the target on the Settings tab and click to Save the scan.
  8. Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl al2_ALAS-2022-1751.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a al2_ALAS-2022-1751.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - al2_ALAS-2022-1751.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state al2_ALAS-2022-1751.nasl -t <IP/HOST>
