CVE-2026-57488 pupnp: Integer truncation in HTTP Content-Length parsing enables request smuggling

pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, rawtoint 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...

CVE-2026-57488

The pupnp SDK (versions prior to 2.0.2 ) contains an integer truncation vulnerability in the raw_to_int function located at upnp/src/genlib/net/http/httpparser.c. The root cause is that Content-Length is parsed using strtol and then cast to a 32-bit int before being stored as an unsigned int. On ...
