* Improved length checks when parsing ASN.1 certificates
* extern "C" additions to header files that were missing them
* Improved checking of return values with TLS extension functions and error codes

* Adjustment of prime testing with --disable-fastmath builds
This release of wolfSSL includes a fix for 2 security vulnerabilities.
There is a fix for a potential buffer overflow case with the TLSv1.3 PSK extension parsing. This affects users that are enabling TLSv1.3 (--enable-tls13). Thanks to Robert Hoerr for the report. The CVE associated with the report is CVE-2019-11873.
There is a fix for the potential leak of nonce sizes when performing ECDSA signing operations. The leak is considered to be difficult to exploit but it could potentially be used maliciously to perform a lattice based timing attack against previous wolfSSL versions. ECC operations with --enable-sp and --enable-sp-asm are not affected, users with private ECC keys in other builds that are performing ECDSA signing operations should update versions of wolfSSL along with private ECC keys. Thanks to Ján Jančár from Masaryk University for the report.

* Fixed a bug in tls_bench.c example test application unrelated to the crypto This release of wolfSSL includes a fix for 2 security vulnerabilities.
or TLS portions of the library. (CVE-2019-6439)
There is a fix for a potential buffer overflow case with the TLSv1.3 PSK extension parsing. This affects users that are enabling TLSv1.3 (--enable-tls13). Thanks to Robert Hoerr for the report. The CVE associated with the report is CVE-2019-11873.
There is a fix for the potential leak of nonce sizes when performing ECDSA signing operations. The leak is considered to be difficult to exploit but it could potentially be used maliciously to perform a lattice based timing attack against previous wolfSSL versions. ECC operations with --enable-sp and --enable-sp-asm are not affected, users with private ECC keys in other builds that are performing ECDSA signing operations should update versions of wolfSSL along with private ECC keys. Thanks to Ján Jančár from Masaryk University for the report.
