NVD Description
Note: Versions mentioned in the description apply only to the upstream wolfssl package and not the wolfssl package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
In wolfSSL before 5.5.2, if callback functions are enabled (via the WOLFSSL_CALLBACKS flag), then a malicious TLS 1.3 client or network attacker can trigger a buffer over-read on the heap of 5 bytes. (WOLFSSL_CALLBACKS is only intended for debugging.)
