CVE-2019-3859

Name of the Vulnerable Software and Affected Versions libssh2 versions prior to 1.8.1

Description The issue is related to an out of bounds read flaw in the libssh2 packet require and libssh2 packet requirev functions of the libssh2 library. This flaw can be exploited by a remote attacker who compromises an SSH server, potentially allowing them to cause a Denial of Service or read data in the client memory.
