- Summary
- wasmtime_trap_code C API function has out of bounds write vulnerability
- Details
-
Impact
There is a bug in Wasmtime's C API implementation where the definition of the
wasmtime_trap_codedoes not match its declared signature in thewasmtime/trap.hheader file. This discrepancy causes the function implementation to perform a 4-byte write into a 1-byte buffer provided by the caller. This can lead to three zero bytes being written beyond the 1-byte location provided by the caller.Patches
This bug has been patched and users should upgrade to Wasmtime 2.0.2.
Workarounds
This can be worked around by providing a 4-byte buffer casted to a 1-byte buffer when calling
wasmtime_trap_code. Users of thewasmtimecrate are not affected by this issue, only users of the C API functionwasmtime_trap_codeare affected.References
