Summary

Details

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.
