Name of the Vulnerable Software and Affected Versions libesmtp versions prior to 0.8.11

Description The issue allows a remote SMTP server to execute arbitrary code or cause a denial of service via long server responses due to a buffer overflow in the read smtp response function of protocol.c. This can lead to a disruption in confidentiality, integrity, and availability of protected information. The exploitation of this issue can be done remotely.

Recommendations For versions prior to 0.8.11, update to version 0.8.11 or later to resolve the issue. As a temporary workaround, consider restricting access to the read smtp response function in protocol.c to minimize the risk of exploitation.
