CVE-2023-29046 Information

Description

Connections to external data sources like e-mail autoconfiguration were not terminated in case they hit a timeout instead those connections were logged. Some connections use user-controlled endpoints which could be malicious and attempt to keep the connection open for an extended period of time. As a result users were able to trigger large amount of egress network connections possibly exhausting network pool resources and lock up legitimate requests. A new mechanism has been introduced to cancel external connections that might access user-controlled endpoints. No publicly available exploits are known.
