Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : OpenEXR vulnerabilities (USN-4418-1)

medium Nessus Plugin ID 138168

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

It was discovered that OpenEXR incorrectly handled certain malformed EXR image files. If a user were tricked into opening a crafted EXR image file, a remote attacker could cause a denial of service, or possibly execute arbitrary code.

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 packages.
