========================================================================== Ubuntu Security Notice USN-3795-3 November 29, 2018
libssh regression ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
USN-3795-1 and USN-3795-2 introduced a regression in libssh.
Software Description: - libssh: A tiny C SSH library
Details:
USN-3795-1 and USN-3795-2 fixed a vulnerability in libssh. The upstream fix introduced a regression. This update fixes the problem.
Original advisory details:
Peter Winter-Smith discovered that libssh incorrectly handled authentication when being used as a server. A remote attacker could use this issue to bypass authentication without any credentials.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.10: libssh-4 0.8.1-1ubuntu0.3
Ubuntu 18.04 LTS: libssh-4 0.8.0~20170825.94fa1e38-1ubuntu0.2
Ubuntu 16.04 LTS: libssh-4 0.6.3-4.3ubuntu0.2
Ubuntu 14.04 LTS: libssh-4 0.6.1-0ubuntu3.5
After a standard system update you need to reboot your computer to make all the necessary changes.
