Attackers can pass atim or mtim values whose sub-second field overflows the seconds field to path_filestat_set_times, fd_filestat_set_times, set-times, or set-times-at, crashing the host.","cvssScore":6.2,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-190"],"vendors":[],"products":[],"references":[{"url":"https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-j2g9-4prp-pf6h","tags":[]},{"url":"https://www.vulncheck.com/advisories/wasmtime-before-36.0.16-37.0.0-before-48.0.3-and-49.0.0-before-49.0.1-host-panic-via-wasi-filesystem-timestamp-overflow","tags":[]}],"exploitRefs":[{"url":"https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-j2g9-4prp-pf6h","tags":[]}],"hasPoc":true,"ai":null}
