EulerOS 2.0 SP5 : libssh2 (EulerOS-SA-2019-2536)

high Nessus Plugin ID 131810

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the libssh2 package installed, the EulerOS installation on the remote host is affected by the following 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libssh2 package.
