Prior to 2.0.2, Transfer-Encoding: chunked causes the HTTP parser in upnp/src/genlib/net/http/httpparser.c to leave parser->content_length at zero while parser_parse_chunky_entity and parser_parse_chunky_body accumulate decoded bytes in parser->msg.entity. The g_maxContentLength checks in http_RecvMessage in upnp/src/genlib/net/http/httpreadwrite.c therefore reject oversized numeric Content-Length bodies but do not enforce the same limit on decoded chunked bodies. A remote peer that can reach a SOAP, GENA, miniserver, or control-point HTTP response path can make the process buffer an entity larger than the configured maximum, causing resource exhaustion and denial of service. This issue is fixed in 2.0.2."}], "lastModified": "2026-10-23T16:07:21.000", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:pupnp_project:pupnp:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0E4F6778-A763-43EF-9981-F6DEED073773", "versionEndExcluding": "2.0.2"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
