Can someone help me to fix issue with "Segmentation fault (core dumped)" on Ubuntu 16.04. Whatever program I am trying to install (e.g. Aptana Studio 3; liclipse_4.0.0) I get this error when running executable file:

Segmentation fault (core dumped)

I've read about this error on Internet and answers says that "A segmentation fault is almost always due to a bug in the program where it occurs". I found it most unlikely that all programs I am trying to install have a bug. It must be something wrong with my system.

The problem is in linux kernel - linux-image-3.13.0-121-generic (in Trusty) and linux-image-4.4.0-81-generic (in Xenial) contains a fix for the Stack Clash vulnerability.

Be careful with kernel updates, which fix this vulnerability. Current patch breaks many java (sun/oracle and openjdk) applications. See Bug #1699772: linux-image-4.4.0-81-generic, linux-image-3.13.0-121-generic Regression: many user-space apps crashing. The solution is to temporary reboot system with old kernel (linux-image-3.13.0-119-generic in Trusty / linux-image-4.4.0-79-generic in Xenial).

Ubuntu kernel developers will prepare new patch in a few days.

UPDATE: Latest updates (at least image-4.4.0-83-generic, linux-image-4.8.0-58-generic, linux-image-4.10.0-26-generic) fix this vulnerability and problems with user-space programs.
