Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES11 host has a package installed that is affected by a vulnerability as referenced in the SUSE- SU-2019:14206-1 advisory.

- 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.
