Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:14943-1 advisory.

- SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has a heap-based buffer overflow in SDL_FillRect in video/SDL_surface.c. (CVE-2019-7637)

- SDL (Simple DirectMedia Layer) through 2.0.12 has an Integer Overflow (and resultant SDL_memcpy heap corruption) in SDL_BlitCopy in video/SDL_blit_copy.c via a crafted .BMP file. (CVE-2020-14409)

- SDL (Simple DirectMedia Layer) through 2.0.12 has a heap-based buffer over-read in Blit_3or4_to_3or4__inversed_rgb in video/SDL_blit_N.c via a crafted .BMP file. (CVE-2020-14410)

- There is a heap overflow problem in video/SDL_pixels.c in SDL (Simple DirectMedia Layer) 2.x to 2.0.18 versions. By crafting a malicious .BMP file, an attacker can cause the application using this library to crash, denial of service or Code execution. (CVE-2021-33657)

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

Solution

Update the affected SDL and / or SDL-32bit packages.

How to Run

Here is how to run the SUSE SLES11 Security Update : SDL (SUSE-SU-2022:14943-1) 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 SuSE Local Security Checks plugin family.
On the right side table select SUSE SLES11 Security Update : SDL (SUSE-SU-2022:14943-1) plugin ID 160097.
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 suse_SU-2022-14943-1.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a suse_SU-2022-14943-1.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - suse_SU-2022-14943-1.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 suse_SU-2022-14943-1.nasl -t <IP/HOST>

Go back to menu.
