CVE-2017-5715
Published: 3 January 2018
Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
From the Ubuntu Security Team
Jann Horn discovered that microprocessors utilizing speculative execution and branch prediction may allow unauthorized memory reads via sidechannel attacks. This flaw is known as Spectre. A local attacker could use this to expose sensitive information, including kernel memory.
Notes
| Author | Note |
|---|---|
| tyhicks | Variant 2, aka "Spectre" |
| mdeslaur | intel-microcode updates were reverted in usn-3531-2 |
| tyhicks | The break-fix lines for this CVE are not complete since a large number of patches are required to mitigate this issue. The commit(s) listed are chosen as placeholders for automated CVE triage purposes. |
| leosilva | Due to the lack of recent CPU models in qemu and the lack of microcode early-loading support in the precise kernel, we do not plan on backporting support for the new flag to QEMU and libvirt at this time. |
