 Package : strongswan Version : 5.7.2-1+deb10u4 CVE ID : CVE-2023-41913

 It was discovered that there was a potential buffer overflow in strongswan, a IPsec-based VPN (Virtual Private Network) server.

 A vulnerability related to processing public Diffie-Hellman key exchange values could have resulted in a buffer overflow and potentially remote code execution as a result.
