Description
OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. In version 3.3.2, applications trust unvalidated dataWindow size values from file headers, which can lead to excessive memory allocation and performance degradation when processing malicious files. This is fixed in version 3.3.3.
