"value": "Wasmer is a web assembly (wasm) Runtime supporting WASIX, WASI and Emscripten. If the preopened directory has a symlink pointing outside, WASI programs can traverse the symlink and access host filesystem if the caller sets both `oflags::creat` and `rights::fd_write`. Programs can also crash the runtime by creating a symlink pointing outside with `path_symlink` and `path_open`ing the link. This issue has been addressed in commit `b9483d022` which has been included in release version 4.3.2. Users are advised to upgrade. There are no known workarounds for this vulnerability."

"value": "Wasmer es un tiempo de ejecuci\u00f3n de ensamblaje web (wasm) que admite WASIX, WASI y Emscripten. Si el directorio preabierto tiene un enlace simb\u00f3lico que apunta hacia afuera, los programas WASI pueden atravesar el enlace simb\u00f3lico y acceder al sistema de archivos del host si la persona que llama configura tanto `oflags::creat` como `rights::fd_write`. Los programas tambi\u00e9n pueden bloquear el tiempo de ejecuci\u00f3n al crear un enlace simb\u00f3lico que apunte hacia afuera con `path_symlink` y `path_open` en el enlace. Este problema se solucion\u00f3 en el commit `b9483d022` que se incluy\u00f3 en la versi\u00f3n 4.3.2. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad."
