Source: GitHub Advisory Database (reviewed) Moderate CVE-2023-43636

Packages

Ecosystem	Package	Affected	Fixed in
Go	github.com/lf-edge/eve/pkg/grub	< 0.0.0-20220708121648-5fef4d92e758	0.0.0-20220708121648-5fef4d92e758

Details

As written in the advisory (Markdown source, shown as plain text).

### Impact Measured boot validates BIOS, grub, kernel cmdline, and initrd but not the entire rootfs. Thus, an attacker can create an EVE-OS rootfs squashfs image with some files modified and take out the disk and replace the existing rootfs image without that being detected by measure boot and remote attestation. ### Patches Fixed in 8.6.0 and 8.12.1-lts ### Workarounds None
