OpenEXR 3.4.9 addresses multiple CVEs including CVE-2026-34379: Misaligned write in LossyDctDecoder_execute leading to undefined behavior (DWA/DWAB decompression). Affected component: LossyDctDecoder in the DWA/DWAB path; root cause is a misaligned write that can cause undefined behavior. This up...

CVE-2026-34379 OpenEXR has a misaligned write in LossyDctDecoder_execute leading to undefined behavior (DWA/DWAB decompression)

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, a misaligned memory write vulnerability exists in LossyDctDecoderexecute in...

unsafe-libyaml unaligned write of u64 on 32-bit and 16-bit platforms

Affected versions allocate memory using the alignment of usize and write data to it of type u64, without using core::ptr::writeunaligned. In platforms with sub-64bit alignment for usize including wasm32 and x86 these writes are insufficiently aligned some of the time. If using an ordinary optimiz...
