0 OpenEXR versions 3.4.0 through 3.4.9 contain a signed integer overflow vulnerability in the HTJ2K decompression path. The vulnerability occurs in the ht_undo_impl() function where a 32-bit signed integer accumulator for bytes-per-line (bpl) can overflow when processing a specially crafted EXR file with a large number of FLOAT channels and maximum width. This overflow can lead to undefined behavior and potentially a heap out-of-bounds write on hosts that allow large memory allocations. Version 3.4.10 includes a fix for this issue.
