Canonical Also Patches Ubuntu 12.04 LTS Against the Stack Clash Vulnerability

Ubuntu 12.04 LTS reached end of life a few weeks ago, on April 28, 2017, but Canonical is now providing ESM (Extended Security Maintenance) updates for those still using the operating system on their machines. That’s why the company is now releasing an updated kernel to fix the security issue known as Stack Clash (CVE-2017-1000364), which was already patched in all the other supported Ubuntu Linux releases. Additionally, the kernel update fixes another security flaw (CVE-2016-4997) that was discovered by Tim Newsham and Jesse Hertz in Linux kernel’s netfilter implementation, which incorrectly performed validations when attempting to handle 32-bit compatibility IPT_SO_SET_REPLACE events on 64-bit systems.
