## This release of wolfSSL includes fixes for X security vulnerabilities. ## This release of wolfSSL includes fixes for 5 security vulnerabilities.
* Place holder. wolfSSL version 4.5.0 contains 5 vulnerability fixes: 2 fixes for TLS 1.3,
2 side channel attack mitigations, and 1 fix for a potential private key
leak in a specific use case.
* In earlier versions of wolfSSL there exists a potential man in the middle
attack on TLS 1.3 clients. Malicious attackers with a privileged network
position can impersonate TLS 1.3 servers and bypass authentication. Users
that have applications with client side code and have TLS 1.3 turned on,
should update to the latest version of wolfSSL. Users that do not have
TLS 1.3 turned on, or that are server side only, are NOT affected by this
report. Thanks to Gerald Doussot from NCC group for the report.
* Denial of service attack on TLS 1.3 servers from repetitively sending
ChangeCipherSpecs messages. This denial of service results from the
relatively low effort of sending a ChangeCipherSpecs message versus the
effort of the server to process that message. Users with TLS 1.3 servers are
recommended to update to the most recent version of wolfSSL which limits the
number of TLS 1.3 ChangeCipherSpecs that can be received in order to avoid
this DoS attack. CVE-2020-12457 was reserved for the report. Thanks to
Lenny Wang of Tencent Security Xuanwu LAB.
* Potential cache timing attacks on public key operations in builds that are
not using SP (single precision). Users that have a system where malicious
agents could execute code on the system, are not using the SP build with
wolfSSL, and are doing private key operations on the system (such as signing
with a private key) are recommended to regenerate private keys and update to
the most recent version of wolfSSL. CVE-2020-15309 is reserved for this
issue. Thanks to Ida Bruhns from Universität zu Lübeck for the report.
* When using SGX with EC scalar multiplication the possibility of side-channel
attacks are present. To mitigate the risk of side channel attacks wolfSSL’s
single precision EC operations should be used instead. Release 4.5.0 turns
this on be default now with SGX builds and in previous versions of wolfSSL
this can be turned on by using the WOLFSSL_SP macros. Thank you to
Alejandro Cabrera Aldaya, Cesar Pereida García and Billy Bob Brumley from
the Network and Information Security Group (NISEC) at Tampere University for
the report.
* Leak of private key in the case that PEM format private keys are bundled in
with PEM certificates into a single file. This is due to the
misclassification of certificate type versus private key type when parsing
through the PEM file. To be affected, wolfSSL would need to have been built
with OPENSSL_EXTRA (--enable-opensslextra). Some build variants such as
--enable-all and --enable-opensslall also turn on this code path, checking
wolfssl/options.h for OPENSSL_EXTRA will show if the macro was used with the
build. If having built with the opensslextra enable option and having placed
PEM certificates with PEM private keys in the same file when loading up the
certificate file, then we recommend updating wolfSSL for this use case and
also recommend regenerating any private keys in the file.

certificate file, then we recommend updating wolfSSL for this use case and
also recommend regenerating any private keys in the file.
