[Buildroot] [PATCH 1/1] package/wolfssl: security bump to version 5.5.0

[Yann E. MORIN]

Fabrice, All,

On 2022-09-04 11:26 +0200, Fabrice Fontaine spake thusly:
> Fix the following security vulnerabilities:
>  - [Low] Fault injection attack on RAM via Rowhammer leads to ECDSA key
>    disclosure. Users doing operations with private ECC keys such as
>    server side TLS connections and creating ECC signatures, who also
>    have hardware that could be targeted with a sophisticated Rowhammer
>    attack should update the version of wolfSSL and compile using the
>    macro WOLFSSL_CHECK_SIG_FAULTS.
>  - [Low] In wolfSSL version 5.3.0 if compiled with
>    --enable-session-ticket and the client has non-empty session cache,
>    with TLS 1.2 there is the possibility oàf a man in the middle passing
>    a large session ticket to the client and causing a crash due to an
>    invalid free. There is also the potential for a malicious TLS 1.3
>    server to crash a client in a similar manner except in TLS 1.3 it is
>    not susceptible to a man in the middle attack. Users on the client
>    side with –enable-session-ticket compiled in and using wolfSSL
>    version 5.3.0 should update their version of wolfSSL.
>  - [Low] If using wolfSSL_clear to reset a WOLFSSL object (vs the normal
>    wolfSSL_free/wolfSSL_new) it can result in runtime issues. This
>    exists with builds using the wolfSSL compatibility layer
>    (--enable-opnesslextra) and only when the application is making use
>    of wolfSSL_clear instead of SSL_free/SSL_new. In the case of a TLS
>    1.3 resumption, after continuing to use the WOLFSSH object after
>    having called wolfSSL_clear, an application could crash. It is
>    suggested that users calling wolfSSL_clear update the version of
>    wolfSSL used.
>  - Potential DoS attack on DTLS 1.2. In the case of receiving a
>    malicious plaintext handshake message at epoch 0 the connection will
>    enter an error state reporting a duplicate message. This affects both
>    server and client side. Users that have DTLS enabled and in use
>    should update their version of wolfSSL to mitigate the potential for
>    a DoS attack.
