Synopsis
The remote Ubuntu host is missing one or more security-related patches.
Description
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.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
Update the affected python-pil and / or python3-pil packages.
