Name of the Vulnerable Software and Affected Versions fwupd (all versions)
Description A PGP signature bypass flaw was found, which could lead to the installation of unsigned firmware. The highest threat from this vulnerability is to confidentiality and integrity. It is theoretically possible but not practical because the Linux Vendor Firmware Service (LVFS) is either not implemented or enabled in versions of fwupd shipped with Red Hat Enterprise Linux 7 and 8. Approximately 500,000 unique IP addresses are affected.
Recommendations As a temporary workaround, consider disabling the signature verification process until a patch is available. Restrict access to the LVFS to minimize the risk of exploitation. Avoid using fwupd until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
