A flaw found in function dataWindowForTile() of IlmImf/ImfTiledMisc.cpp. An attacker who is able to submit a crafted file to be processed by OpenEXR could trigger an integer overflow, leading to an out-of-bounds write on the heap. The greatest impact of this flaw is to application availability, with some potential impact to data integrity as well.
