| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 15.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in libssh. Software Description: - libssh: A tiny C SSH library Details: Mariusz Ziulek discovered that libssh incorrectly handled certain packets. A remote attacker could possibly use this issue to cause libssh to crash, resulting in a denial of service. (CVE-2015-3146) Aris Adamantiadis discovered that libssh incorrectly generated ephemeral secret keys of 128 bits instead of the recommended 1024 or 2048 bits when using the diffie-hellman-group1 and diffie-hellman-group14 methods. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. (CVE-2016-0739) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 15.10: Ubuntu 14.04 LTS: Ubuntu 12.04 LTS: In general, a standard system update will make all the necessary changes.
