Ubuntu Security Notice USN-6232-1
July 20, 2023
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)
- Ubuntu 14.04 LTS (Available with Ubuntu Pro)
wkhtmltopdf could be made to expose sensitive information if it opened a
specially crafted file.
- wkhtmltopdf: Command line utility to convert html to pdf using WebKit
It was discovered that wkhtmltopdf was not properly enforcing the
same-origin policy when processing certain HTML files. If a user or
automated system using wkhtmltopdf were tricked into processing a
specially crafted HTML file, an attacker could possibly use this issue to
expose sensitive information.
The problem can be corrected by updating your system to the following
Ubuntu 20.04 LTS:
Ubuntu 18.04 LTS (Available with Ubuntu Pro):
Ubuntu 16.04 LTS (Available with Ubuntu Pro):
Ubuntu 14.04 LTS (Available with Ubuntu Pro):
