libwasmtime -- host panic with fd_renumber WASIp1 function

2025-07-20 · CVE-2025-53901 · VuXML entry

WasmTime development team reports: A bug in Wasmtime's implementation of the WASIp1 set of import functions can lead to a WebAssembly guest inducing a panic in the host (embedder).

Affected versions

• libwasmtime >= 24.0.0 < 24.0.4; >= 33.0.0 < 33.0.2; >= 34.0.0 < 34.0.2

By system

0 still vulnerable, 1 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
