Vulnerability Information

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-2975 advisory.

- There's a flaw in openjpeg's t2 encoder in versions prior to 2.4.0. An attacker who is able to provide crafted input to be processed by openjpeg could cause a null pointer dereference. The highest impact of this flaw is to application availability. (CVE-2020-27842)

- A flaw was found in OpenJPEG in versions prior to 2.4.0. This flaw allows an attacker to provide specially crafted input to the conversion or encoding functionality, causing an out-of-bounds read. The highest threat from this vulnerability is system availability. (CVE-2020-27843)

- Integer Overflow in OpenJPEG v2.4.0 allows remote attackers to crash the application, causing a Denial of Service (DoS). This occurs when the attacker uses the command line option -ImgDir on a directory that contains 1048576 files. (CVE-2021-29338)

- A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input directory with a large number of files. When it fails to allocate a buffer to store the filenames of the input directory, it calls free() on an uninitialized pointer, leading to a segmentation fault and a denial of service. (CVE-2022-1122)

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 openjpeg2 packages.

For Debian 9 stretch, these problems have been fixed in version 2.1.2-1.1+deb9u7.

How to Run

Here is how to run the Debian DLA-2975-1 : openjpeg2 - LTS security update as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
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-2975-1 : openjpeg2 - LTS security update plugin ID 159625.
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-2975.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a debian_DLA-2975.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-2975.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-2975.nasl -t <IP/HOST>

Go back to menu.
