Packages

Go github.com/lf-edge/eve < 0.0.0-20230519072751-977f42b07fa9 0.0.0-20230519072751-977f42b07fa9

Details

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

### Impact Config partition measurement was moved from PCR 13 to PCR 14 in a commit, but PCR 14 was not added to the list of PCRs that seal/unseal the vault key. As a result, an attacker can remove the disk, use another server to modify the files in the config partition, and then re-insert the disk. ### Patches Fixed in EVE version 9.4.3-lts ### Workarounds None (apart from preventing physical access to the device) ### Resources https://help.zededa.com/hc/en-us/articles/43295940828827-TPM-PCR-Index-Security-Implications https://github.com/lf-edge/eve/commit/d9383a7ee4e1c39f5c8c6d4a63cb2ebd00695e8a
