      <title>CVE-2024-38358 — Symlink bypasses filesystem sandbox in wasmer</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2024-38358</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; wasmerio wasmer, wasmer&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>
