USN-2478-1: libssh vulnerability

19 January 2015

libssh could be made to crash if it received specially crafted network traffic.



  • libssh - A tiny C SSH library


It was discovered that libssh incorrectly handled certain kexinit packets.
A remote attacker could possibly use this issue to cause libssh to crash,
resulting in a denial of service.

Update instructions

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

Ubuntu 14.10
Ubuntu 14.04
Ubuntu 12.04

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