At the time of disclosure, Intel was not aware of any reports that L1TF has been used in real-world exploits. These vulnerabilities use a speculative execution side-channel method which Intel is referring to as L1 Terminal Fault (L1TF). These vulnerabilities, when exploited for malicious purposes, have the potential to allow the improper gathering of sensitive data. On 14 August 2018, Intel disclosed new vulnerabilities that impact processors which are supported on certain HPE platforms. Ripple20 Vulnerability – Multiple Vulnerabilities Affecting the Treck TCP/IP Stack (Multiple CVEs).Impact assessment for HPE Products is available here.Īdditional details on HPE Support Centre. HPE will provide documentation about product impact and resolution below. Impacted HPE products will also have updates that align with these GRUB2 and DBX updates.Īdditionally, there is a similar vulnerability mentioned in the BootHole disclosure and HPE is addressing this issue, which has been assigned CVE-2020-7205. To prevent this vulnerability, an updated GRUB2 and an updated Forbidden Signature Database (DBX) are being made available from relevant OS vendors, and must be applied to the system. The vulnerability can lead to circumventing the Secure Boot process, on systems where Secure Boot is enabled.

A system is vulnerable to the BootHole issue when a signed GRUB2 bootloader with the vulnerable code is permitted to execute by the UEFI Allowed Signature Database (DB).

On 29 July, a researcher disclosed a vulnerability in Linux GRUB2 bootloaders called “BootHole” ( CVE-2020-10713 and CVE-2020-15705).
