Threats affecting pkg:github/willamowius/gnugk

GNU Gatekeeper (gnugk) versions before 5.16 have an out-of-bounds read vulnerability in the H46024Socket::ReceivedProbePacket() function. This flaw allows remote attackers to cause a heap over-read by sending short probe packets, specifically short application-defined RTCP packets during H.460.24 probing. Exploitation may lead to reading beyond allocated heap memory and potentially crashing the gatekeeper.

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.
