USN-7353-1: PlantUML vulnerability
17 March 2025

PlantUML could be made to crash or run programs as your login if it opened a specially crafted UML file.

Releases
Ubuntu 24.10 Ubuntu 24.04 LTS Ubuntu 22.04 LTS Ubuntu 20.04 LTS Ubuntu 18.04 ESM Ubuntu 16.04 ESM

Packages
plantuml - text-to-UML converter

Details
Tobias S. Fink discovered that PlantUML was susceptible to cross-site
scripting attacks (XSS) in instances where SVG images were rendered.
An attacker could possibly use this issue to cause PlantUML to crash,
resulting in a denial of service, or the execution of arbitrary code.

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

Ubuntu 24.10

• plantuml - 1:1.2020.2+ds-5ubuntu0.1
  Ubuntu 24.04
• plantuml - 1:1.2020.2+ds-3ubuntu1.1
  Ubuntu 22.04
