high Nessus Plugin ID 147277

Language:

Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has libssh2 packages installed that are affected by a vulnerability:

 - In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. (CVE-2019-17498)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL libssh2 packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
