Synopsis

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

Description

The version of gcc installed on the remote host is prior to 7.3.1-14. The version of gcc10 installed on the remote host is prior to 10.3.1-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1784 advisory.

- An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It permits the visual reordering of characters via control sequences, which can be used to craft source code that renders different logic than the logical ordering of tokens ingested by compilers and interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted vulnerabilities are introduced invisibly to human reviewers. (CVE-2021-42574)

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 gcc10' to update your system. Run 'yum update gcc' to update your system.

How to Run

Here is how to run the Amazon Linux 2 : gcc10, gcc (ALAS-2022-1784) 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 : gcc10, gcc (ALAS-2022-1784) plugin ID 160265.
  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-2022-1784.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a al2_ALAS-2022-1784.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-2022-1784.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-2022-1784.nasl -t <IP/HOST>

Go back to menu.
