Ubuntu Security Notice USN-6353-1
September 07, 2023

plib vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)


PLIB could be made to execute arbitrary code if it opens a specially
crafted TGA file.

Software Description:
- plib: Portability Libraries: Development package


Wooseok Kang discovered that PLIB did not properly manage memory under
certain circumstances. If a user were tricked into opening a specially
crafted TGA file, an attacker could possibly use this issue to cause
applications using PLIB to crash, resulting in a denial of service, or
possibly execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.04 LTS:
   libplib1                        1.8.5-8ubuntu0.20.04.1

Ubuntu 18.04 LTS (Available with Ubuntu Pro):
   libplib1                        1.8.5-8ubuntu0.18.04.1~esm1

Ubuntu 16.04 LTS (Available with Ubuntu Pro):
   libplib1                        1.8.5-7ubuntu0.1~esm1

In general, a standard system update will make all the necessary changes.
