22 April 2024
Pillow could be made to crash or run programs as an administrator if it opened a specially crafted file.
Releases
Packages
- pillow-python2 - Python Imaging Library (Pillow fork)
Details
USN-6744-1 fixed a vulnerability in Pillow (Python 3). This update
provides the corresponding updates for Pillow (Python 2) in
Ubuntu 20.04 LTS.
Original advisory details:
Hugo van Kemenade discovered that Pillow was not properly performing
bounds checks when processing an ICC file, which could lead to a buffer
overflow. If a user or automated system were tricked into processing a
specially crafted ICC file, an attacker could possibly use this issue
to cause a denial of service or execute arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04
-
python-pil
-
6.2.1-3ubuntu0.1~esm2
Available with Ubuntu Pro
In general, a standard system update will make all the necessary changes.
