Mitigation Strategies

To mitigate this vulnerability, you should update the Secure Access macOS client to version 14.50 or later, as versions prior to 14.50 are affected by this out-of-bounds read vulnerability.

Since the vulnerability is triggered by a malformed packet sent from a modified server, avoid connecting to untrusted or suspicious servers until the client is updated.
