{"id":"CVE-2026-57488","published":"2026-10-16T16:18:44.823","lastModified":"2026-10-16T20:17:23.460","description":"pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, raw_to_int in upnp/src/genlib/net/http/httpparser.c parses Content-Length with strtol and casts the resulting long to a 32-bit int before the caller stores it as unsigned int. On LP64 systems, values greater than INT_MAX can truncate or wrap, so the HTTP parser can accept a body length different from the declared value. A remote adjacent-network peer can use the resulting parser disagreement to leave bytes to be interpreted as another request in persistent or proxied contexts, or can make a worker wait for an extremely large body and cause denial of service. This issue is fixed in 2.0.2.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","cwes":["CWE-190","CWE-444"],"vendors":[],"products":[],"references":[{"url":"https://github.com/pupnp/pupnp/commit/de9602aef34ff722f3630d66c9be8eaa0aa9f012","tags":[]},{"url":"https://github.com/pupnp/pupnp/releases/tag/release-2.0.2","tags":[]},{"url":"https://github.com/pupnp/pupnp/security/advisories/GHSA-g6c2-x4r9-352g","tags":[]},{"url":"https://github.com/pupnp/pupnp/security/advisories/GHSA-g6c2-x4r9-352g","tags":[]}],"exploitRefs":[{"url":"https://github.com/pupnp/pupnp/commit/de9602aef34ff722f3630d66c9be8eaa0aa9f012","tags":[]},{"url":"https://github.com/pupnp/pupnp/releases/tag/release-2.0.2","tags":[]},{"url":"https://github.com/pupnp/pupnp/security/advisories/GHSA-g6c2-x4r9-352g","tags":[]},{"url":"https://github.com/pupnp/pupnp/security/advisories/GHSA-g6c2-x4r9-352g","tags":[]}],"hasPoc":true,"ai":null}
