Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 13.10 Summary: OpenSSH could be made to run programs if it received specially crafted network traffic from an authenticated user. Software Description: - openssh: secure shell (SSH) client, for secure access to remote machines Details: Markus Friedl discovered that OpenSSH incorrectly handled memory when the AES-GCM cipher was used. A remote authenticated attacker could use this issue to execute arbitrary code as their user, possibly bypassing shell or command restrictions. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 13.10: In general, a standard system update will make all the necessary changes.
