Ubuntu Security Notice USN-4676-1
January 05, 2021

openexr vulnerabilities

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

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


Several security issues were fixed in OpenEXR.

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:

Ubuntu 20.04 LTS:
  libopenexr24                    2.3.0-6ubuntu0.3
  openexr                         2.3.0-6ubuntu0.3

Ubuntu 18.04 LTS:
  libopenexr22                    2.2.0-11.1ubuntu1.4
  openexr                         2.2.0-11.1ubuntu1.4

Ubuntu 16.04 LTS:
  libopenexr22                    2.2.0-10ubuntu2.4
  openexr                         2.2.0-10ubuntu2.4

In general, a standard system update will make all the necessary changes.
