Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-phcg-h58r-gmcq. This link is maintained to preserve external references.
Original Description
As noted in the “VTPM.md” file in the eve documentation, “VTPM is a server listening on port 8877 in EVE, exposing limited functionality of the TPM to the clients. VTPM allows clients to execute tpm2-tools binaries from a list of hardcoded options” The communication with this server is done using protobuf, and the data is comprised of 2 parts:
-
Header
-
Data
When a connection is made, the server is waiting for 4 bytes of data, which will be the header, and these 4 bytes would be parsed as uint32 size of the actual data to come.
Then, in the function “handleRequest” this size is then used in order to allocate a payload on the stack for the incoming data.
As this payload is allocated on the stack, this will allow overflowing the stack size allocated for the relevant process with freely controlled data.
- An attacker can crash the system.
- An attacker can gain control over the system, specifically on the “vtpm_server” process which has very high privileges.
