Releases

• Ubuntu 20.04 LTS
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• plib - Portability Libraries: Development package

Details

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

• libplib1 - 1.8.5-8ubuntu0.20.04.1

Ubuntu 18.04

• libplib1 - 1.8.5-8ubuntu0.18.04.1~esm1
  Available with Ubuntu Pro

Ubuntu 16.04

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