UBUNTU-CVE-2026-44663

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.4.0 through 3.4.11, an integer overflow in htundoimpl in src/lib/OpenEXRCore/internalht.cpp leads to a heap-buffer overflow when decoding a crafted...

UBUNTU-CVE-2026-45696

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.4.0 through 3.4.11, the HTJ2K High-Throughput JPEG 2000 decoder, htundoimpl in OpenEXRCore is vulnerable to a heap-buffer-overflow READ. The htundoimp...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the htundoimpl function when decoding a specially crafted HTJ2K-compressed EXR file. An attacker can cause a heap out-of-bounds write by supplying a file with a large decode-channelsi.width value that...

CVE-2026-45696

CVE-2026-45696 affects OpenEXR 3.4.0–3.4.11, where the HTJ2K decoder’s ht_undo_impl() can perform a heap-buffer-overflow READ due to a width mismatch between the EXR codestream and the declared line width. The decoder copies 32-bit samples from cur_line->i32[] without validating the OpenJPH li...

CVE-2026-44663

OpenEXR CVE-2026-44663 is a heap-buffer overflow in the HTJ2K decoder (ht_undo_impl) caused by 32-bit signed overflow when multiplying decode->channels[i].width by bytes_per_element during HTJ2K decoding. This occurs in OpenEXR 3.4.0–3.4.11 and can lead to a heap out-of-bounds write when handl...
