Medium (6.8) in openexr openexr. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in openexr 3.3.3.
OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. Version 3.3.2 is vulnerable to a heap-based buffer overflow during a read operation due to bad pointer math when decompressing DWAA-packed scan-line EXR files with a maliciously forged chunk. This is fixed in version 3.3.3.
