USN-3531-3: intel-microcode update<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
The system could be made to expose sensitive information.<\/p>\n
Jann Horn discovered that microprocessors utilizing speculative execution
\nand branch prediction may allow unauthorized memory reads via sidechannel
\nattacks. This flaw is known as Spectre. A local attacker could use this to
\nexpose sensitive information, including kernel memory. (CVE-2017-5715)<\/p>\n
This update provides the corrected microcode updates required for the
\ncorresponding Linux kernel updates.<\/p>\n
The problem can be corrected by updating your system to the following package versions:<\/p>\n
