Name of the Vulnerable Software and Affected Versions fetchmail versions 5.9.9 through 6.3.19

Description The issue allows remote servers to cause a denial of service by acknowledging a STARTTLS or STLS request but not sending additional packets, resulting in an application hang.

Recommendations For fetchmail versions 5.9.9 through 6.3.19, consider implementing a timeout mechanism for STARTTLS and STLS requests to prevent the application from hanging indefinitely. As a temporary workaround, restrict access to untrusted servers to minimize the risk of exploitation.
