How to fix?

Upgrade Debian:10 libssh2 to version 1.8.0-2.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libssh2 package and not the libssh2 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

An out of bounds read flaw was discovered in libssh2 before 1.8.1 when a specially crafted SFTP packet is received from the server. A remote attacker who compromises a SSH server may be able to cause a Denial of Service or read data in the client memory.
