CVE-2023-43632
CVSS 3.1 Score 9.9 of 10 (high)
Details
Summary
CVE-2023-43632 is a vulnerability affecting the VTPM server in EVE, which listens on port 8877 and exposes limited TPM functionality to clients. The communication between the server and clients is conducted using protobuf. Upon connection, the server expects a 4-byte header indicating the size of the data to follow. In the function "handleRequest," this header size is used to allocate a payload on the stack for the incoming data. Due to insufficient bounds checking, an attacker can provide maliciously crafted data to overflow the stack, resulting in either a system crash or potentially gaining control over the "vtpm_server" process with high privileges.
