CVE-2022-39393

Wasmtime vulnerability CVE-2022-39393: prior to versions 2.0.2 and 1.0.2, a bug in the pooling instance allocator can cause the initial heap snapshot of a prior instance to be visible to the next instance when reusing linear memory. This data leakage between instances can lead to information expo...

CVE-2022-39393 Wasmtime vulnerable to data leakage between instances in the pooling allocator

Wasmtime is a standalone runtime for WebAssembly. Prior to versions 2.0.2 and 1.0.2, there is a bug in Wasmtime's implementation of its pooling instance allocator where when a linear memory is reused for another instance the initial heap snapshot of the prior instance can be visible, erroneously ...

CVE-2022-39394 wasmtime_trap_code C API function has out of bounds write vulnerability

Wasmtime is a standalone runtime for WebAssembly. Prior to version 2.0.2, there is a bug in Wasmtime's C API implementation where the definition of the wasmtimetrapcode does not match its declared signature in the wasmtime/trap.h header file. This discrepancy causes the function implementation to...

CVE-2022-39392

Wasmtime is a standalone runtime for WebAssembly. Prior to version 2.0.2, there is a bug in Wasmtime's implementation of its pooling instance allocator when the allocator is configured to give WebAssembly instances a maximum of zero pages of memory. In this configuration, the virtual memory mappi...
