Commit Message

Petr Štetiar Oct. 5, 2022, 9:46 a.m. UTC 
Fixes denial of service attack and buffer overflow against TLS 1.3
servers using session ticket resumption. When built with
--enable-session-ticket and making use of TLS 1.3 server code in
wolfSSL, there is the possibility of a malicious client to craft a
malformed second ClientHello packet that causes the server to crash.

This issue is limited to when using both --enable-session-ticket and TLS
1.3 on the server side. Users with TLS 1.3 servers, and having
--enable-session-ticket, should update to the latest version of wolfSSL.

Thanks to Max at Trail of Bits for the report and "LORIA, INRIA, France"
for research on tlspuffin.
