USN-4430-1: Pillow vulnerabilities

Releases

• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• pillow - Python Imaging Library

Details

It was discovered that Pillow incorrectly handled certain image files. If
a user or automated system were tricked into opening a specially-crafted
image file, a remote attacker could possibly cause Pillow to crash,
resulting in a denial of service.

Update instructions

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

Ubuntu 18.04

• python-pil - 5.1.0-1ubuntu0.3
• python3-pil - 5.1.0-1ubuntu0.3

Ubuntu 16.04

• python-pil - 3.1.2-0ubuntu1.4
• python3-pil - 3.1.2-0ubuntu1.4

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