Description

A flaw was found in OpenEXR, a widely used image storage format. A remote attacker could exploit a missing bounds check vulnerability by crafting a malicious EXR file. By manipulating a specific attribute in the file header, an attacker can trigger an integer overflow, causing the application to unexpectedly terminate. This leads to a Denial of Service (DoS) for systems processing the malformed image file.
