Name of the Vulnerable Software and Affected Versions No specific software or versions are mentioned in the provided descriptions.

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 a large amount of egress network connections, possibly exhausting network pool resources and locking 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.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
