medium Nessus Plugin ID 144746

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4676-1 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
