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.","state":0,"publishedAt":"2026-10-16T15:34:49.625+00:00","modifiedAt":"2026-10-16T19:08:25.462+00:00","affected":[{"ecosystem":"Vendor product","name":"pupnp","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"pupnp\",\n                    \"product\": \"pupnp\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.0.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","score":7.1,"severity":"HIGH"}],"references":["https://github.com/pupnp/pupnp/security/advisories/GHSA-g6c2-x4r9-352g","https://github.com/pupnp/pupnp/commit/de9602aef34ff722f3630d66c9be8eaa0aa9f012","https://github.com/pupnp/pupnp/releases/tag/release-2.0.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-57488","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-57488","identifiers":["CVE-2026-57488"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
