==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10
- Ubuntu 17.04
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Summary:
Firefox could be made to expose sensitive information.
Software Description:
- firefox: Mozilla Open Source web browser
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).

package versions:
