Description
This security bulletin contains information about 1 security vulnerability.
1) Resource management error (CVE-ID: CVE-2020-15166)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources with the application when processing TCP requests. If a raw TCP socket is opened and connected to an endpoint that is fully configured with CURVE/ZAP, legitimate clients will not be able to exchange any message. Handshakes complete successfully, and messages are delivered to the library, but the server application never receives them.Remediation
