USN-4219-1: libssh vulnerability

10 December 2019

libssh could be made to run programs under certain conditions.

Releases

Packages

  • libssh - A tiny C SSH library

Details

It was discovered that libssh incorrectly handled certain scp commands. If
a user or automated system were tricked into using a specially-crafted scp
command, a remote attacker could execute arbitrary commands on the server.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.10
Ubuntu 19.04
Ubuntu 18.04
Ubuntu 16.04

In general, a standard system update will make all the necessary changes.
