Releases

Packages

Details

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.

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

Ubuntu 18.04

• openexr - 2.2.0-11.1ubuntu1.7
• libopenexr22 - 2.2.0-11.1ubuntu1.7
