Descripción
*** Pendiente de traducción *** GNU Gatekeeper (gnugk) before 5.16 contains an out-of-bounds read vulnerability in ParseRTCP() in ProxyChannel.cxx that allows remote RTP peers to read heap memory past received packets. Attackers can send RTCP SDES items lacking a NUL byte to the media proxy port during proxied H.323 calls with EnableRTCPStats enabled, crashing the gatekeeper.
