Vulnerability Information

Severity: Critical
Vulnerability Published: 2022-02-11
Patch Published: 2022-04-28
CVE [?]: CVE-2022-23772, CVE-2022-23806, CVE-2022-24921

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2986 advisory.

- Rat.SetString in math/big in Go before 1.16.14 and 1.17.x before 1.17.7 has an overflow that can lead to Uncontrolled Memory Consumption. (CVE-2022-23772)

- Curve.IsOnCurve in crypto/elliptic in Go before 1.16.14 and 1.17.x before 1.17.7 can incorrectly return true in situations with a big.Int value that is not a valid field element. (CVE-2022-23806)

- regexp.Compile in Go before 1.16.15 and 1.17.x before 1.17.8 allows stack exhaustion via a deeply nested expression. (CVE-2022-24921)

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

Solution

Upgrade the golang-1.8 packages.

For Debian 9 stretch, these problems have been fixed in version 1.8.1-1+deb9u5.

Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Debian Local Security Checks plugin family.
On the right side table select Debian DLA-2986-1 : golang-1.8 - LTS security update plugin ID 160303.
Specify the target on the Settings tab and click to Save the scan.
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 debian_DLA-2986.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a debian_DLA-2986.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - debian_DLA-2986.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 debian_DLA-2986.nasl -t <IP/HOST>

Go back to menu.
