Ubuntu Security Notice USN-4418-1
July 06, 2020

openexr vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS
- Ubuntu 19.10
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS


OpenEXR could be made to crash or run programs if it opened a specially
crafted file.

Software Description:
- openexr: tools for the OpenEXR image format


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.

Update instructions:

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