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 way SSH packets are parsed, specifically when the padding length value is greater than the packet length. This could allow a remote attacker who compromises a SSH server to cause a Denial of Service or read data in the client memory. The vulnerability is associated with errors in processing inconsistencies in the length parameter, which can be exploited by a remote attacker to gain unauthorized access to protected information or cause a service disruption.
Recommendations
For versions prior to 1.8.1, update to version 1.8.1 or later to resolve the issue. As a temporary workaround, consider restricting access to SSH servers until the update is applied.
