Details

It was discovered that speculative execution performed by modern CPUs
could leak information through a timing side-channel attack, and that
this could be exploited in web browser JavaScript engines. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit this to obtain sensitive information from other
domains, bypassing same-origin restrictions. (CVE-2017-5715,
CVE-2017-5753, CVE-2017-5754).

Update instructions

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

Ubuntu 17.10
Ubuntu 17.04
Ubuntu 16.04
Ubuntu 14.04

After a standard system update you need to restart Firefox to make
all the necessary changes.
