Name of the Vulnerable Software and Affected Versions
OpenEXR versions 3.4.0 through 3.4.8
Description
A missing bounds check on the
dataWindow attribute in EXR file headers can lead to a signed integer overflow in the generic unpack() function. Setting dataWindow.min.x to a large negative value causes OpenEXRCore to calculate an excessively large image width. This width is then used in a signed integer multiplication, resulting in an overflow and process termination via SIGILL and UBSan.Recommendations
Update to version 3.4.9 or later.
