Critical vulnerability fixed in SNIProxy
Talos Intelligence - https://talosintelligence.com/vulnerability_reports/TALOS-2023-1731
If your SNIProxy configuration contains wildcards, an attacker can use a buffer overflow vulnerability to achieve arbitrary code execution or a denial of service.
When HTTP, TLS, or DTLS packages are handled by the wildcard backend, a malicious packet can trigger a buffer copy without checking the size of the input (CWE-120 Classic Buffer Overflow).
The Centre for Cybersecurity Belgium recommends system administrators to patch vulnerable systems as soon as possible and to analyse system and network logs for any suspicious activity.
Update the installation to the latest version:
* Version 0.6.1 or newer
