"The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the
openSUSE-SU-2021:3004-1 advisory.
- A flaw was found in the libtpms code that may cause access beyond the boundary of internal buffers. The
vulnerability is triggered by specially-crafted TPM2 command packets that then trigger the issue when the
state of the TPM2's volatile state is written. The highest threat from this vulnerability is to system
availability. This issue affects libtpms versions before 0.8.5, before 0.7.9 and before 0.6.6.
