CVE-2021-3477 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:8.
NVD Description
Note: Versions mentioned in the description apply only to the upstream mingw-OpenEXR package and not the mingw-OpenEXR package as distributed by RHEL.
There's a flaw in OpenEXR's deep tile sample size calculations in versions before 3.0.0-beta. An attacker who is able to submit a crafted file to be processed by OpenEXR could trigger an integer overflow, subsequently leading to an out-of-bounds read. The greatest risk of this flaw is to application availability.
