This Affects:
wolfSSL.wolfsslTL;DR
wolfSSL_d2i_SSL_SESSION() deserializes session blobs with SESSION_CERTS enabled using certificate and session identifier lengths from untrusted input without sufficient bounds checks, allowing heap corruption when a malicious session is loaded from an external source. Internal sessions are not affected. The fix validates lengths before copying into fixed-size buffers.
