commit: https://git.buildroot.net/buildroot/commit/?id=a335d32a5f31dec4f23c89ce9f496fac6eba3d69
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Extract from release announcement:

- (2.9, 2.7, 2.1) Fixed an issue in the X.509 module which could lead
to a buffer overread during certificate validation. Additionally, the
issue could also lead to unnecessary callback checks being made or to
some validation checks to be omitted. The overread could be triggered
remotely, while the other issues would require a non DER-compliant
certificate to be correctly signed by a trusted CA, or a trusted CA with
a non DER-compliant certificate. Found by luocm. Fixes #825.

- (2.9, 2.7, 2.1) Fixed the buffer length assertion in the
ssl_parse_certificate_request() function which could lead to an
arbitrary overread of the message buffer. The overreads could be caused
by receiving a malformed algorithms section which was too short. In
builds with debug output, this overread data was output with the debug
data.

- (2.9, 2.7, 2.1) Fixed a client-side bug in the validation of the
server's ciphersuite choice which could potentially lead to the client
accepting a ciphersuite it didn't offer or a ciphersuite that could not
be used with the TLS or DTLS version chosen by the server. This could
lead to corruption of internal data structures for some configurations.
