Description Vladimir Vasilev 2026-10-15 17:40:47 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

miniupnpc through 2.3.3 contains a one-byte heap out-of-bounds read vulnerability in the minixml parseelt function's namespace-prefix handling that skips an end-of-buffer check after advancing past ':'. A malicious or spoofed UPnP gateway on the local network can send a device description or SOAP reply ending in ':' within an element name to crash the client.
