There's a flaw in OpenEXR's ImfDeepScanLineInputFile functionality in versions prior to 3.0.5. An attacker who is able to submit a crafted file to an application linked with OpenEXR could cause an out-of-bounds read. The greatest risk from this flaw is to application availability.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
