## Vulnerabilities
|
|
|
-* [Med] 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, found by Lucca Hirschi from LORIA, Inria, France with the tlspuffin tool developed partly at LORIA and Trail of Bits. CVE-2022-39173
|
|
|
+* [Med] In the case that the WOLFSSL_CALLBACKS macro is set when building wolfSSL, there is a potential heap over read of 5 bytes when handling TLS 1.3 client connections. This heap over read is limited to wolfSSL builds explicitly setting the macro WOLFSSL_CALLBACKS, the feature does not get turned on by any other build options. The macro WOLFSSL_CALLBACKS is intended for debug use only, but if having it enabled in production, users are recommended to disable WOLFSSL_CALLBACKS. Users enabling WOLFSSL_CALLBACKS are recommended to update their version of wolfSSL. Thanks to Lucca Hirschi and Steve Kremer from LORIA, Inria and Max Ammann from Trail of Bits for finding and reporting the bug with the tlspuffin tool developed partly at LORIA and Trail of Bits.
