We are currently using Tectia SSH server 6.1.8 and would like to know whether it is supported. In the wake of Heartbleed vulnerability, could you comment whether this version (6.1) is exposed to any vulnerabilities and whether we need to upgrade to the latest version (6.4)?

Thanks in advance,

There is a very nasty vulnerability in Unix versions of the product of your version. It has been made public in Dec. 2012. See here. It has been fixed in 6.1.13. There are also details on this forum.

Other than that there is no known vulnerability.

Current long term supported version is 6.3.x. Development (but stable) version is 6.4.x. The mentioned vulnerability from 2012 has been also fixed in 6.0.x. So I believe SSH will patch vulnerabilities in 6.1.x versions still for some time. However, the only fully supported versions are 6.3 and 6.4.

With regards,
