Multicloud Defense Gateway Fixes and Enhancements Version 23.08 Version 23.08-17-b1 September 27, 2024

Last updated: May 29, 2025

Version 23.08-17-b1 September 27, 2024

This is a hotfix.

Fixes

The following fix is included in this hotfix:

Fixes an issue where the gateway could not retrieve the SNI from a TLS Client Hello message causing the gateway to close the connection with a TCP RST. This is caused by a change made in Chrome in April 2024 to shift to Post-Quantum Cryptography. With this change, the Client Hello is larger than 1415 bytes, which can result in an inability to retrieve the Server Name Indication (SNI), which is used by the proxy to determine what certificate to issue. The fix ensures the proxy can support Client Hello sizes greater than 1415 bytes.
