SUSE CVE-2026-34589

OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. From 3.2.0 to before 3.2.7, 3.3.9, and 3.4.9, the DWA lossy decoder constructs temporary per-component block pointers using signed 32-bit arithmetic. Fo...

CVE-2026-34589

A flaw was found in OpenEXR. The DWA lossy decoder, responsible for processing EXR image files, incorrectly handles large image widths. This occurs because temporary block pointers are constructed using signed 32-bit arithmetic, which can overflow. A remote attacker could exploit this by providin...

CVE-2026-34588

A flaw was found in OpenEXR, an image storage format for the motion picture industry. A remote attacker could exploit an integer overflow vulnerability in the internalexrundopiz function by providing a specially crafted EXR file. This flaw leads to out-of-bounds reads and writes, which may allow...

CVE-2026-34380

A flaw was found in OpenEXR, an image storage format library. A remote attacker could exploit a signed integer overflow vulnerability in the undopxr24impl function when processing a specially crafted EXR image file. This overflow can cause the application to write pixel data beyond its allocated...

OpenEXR has heap-buffer-overflow via signed integer underflow in ImfContextInit.cpp

Summary A heap-buffer-overflow OOB read occurs in the istreamnonparallelread function in ImfContextInit.cpp when parsing a malformed EXR file through a memory-mapped IStream. A signed integer subtraction produces a negative value that is implicitly converted to sizet, resulting in a massive lengt...
