NVD Description

Note: Versions mentioned in the description apply only to the upstream libssh2-debugsource package and not the libssh2-debugsource package as distributed by Centos.

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.
