EulerOS 2.0 SP3 : libssh2 (EulerOS-SA-2020-1405)

high Nessus Plugin ID 135534

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 :

- A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8. When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of the function, it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target.(CVE-2019-14889)

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.
