CVE-2026-5187

CVE-2026-5187 affects wolfSSL’s wolfcrypt DecodeObjectId() in asn.c, with two potential heap out-of-bounds writes. First, a bounds check validates only one slot before writing two OID arcs (out[0], out[1]), allowing a 2-byte OOB write when outSz == 1. Second, callers pass sizeof(decOid) (64 bytes...

OpenEXR: DWA Lossy Decoder Heap Out-of-Bounds Write

Summary The DWA lossy decoder constructs temporary per-component block pointers using signed 32-bit arithmetic. For a large enough width, the calculation overflows and later decoder stores operate on a wrapped pointer outside the allocated rowBlock backing store. This bug is reachable from the...
