Vavoom 1.19.1 and earlier allows remote attackers to cause a denial of service (infinite loop) via (1) a packet with no data or (2) a large packet, which prevents Vavoom from discarding the packet from the socket.

Buffer overflow in Vavoom 1.19.1 and earlier allows remote attackers to cause a denial of service (application crash) via an invalid comprLength value in a compressed packet.

Format string vulnerability in the Say command in sv_main.cpp in Vavoom 1.24 and earlier allows remote attackers to execute arbitrary code via format string specifiers in a chat message, related to a call to the BroadcastPrintf function.

Buffer overflow in the VThinker::BroadcastPrintf function in p_thinker.cpp in Vavoom 1.24 and earlier allows remote attackers to execute arbitrary code via (1) a long string in a chat message and possibly (2) a long name field.

The VStr::Resize function in str.cpp in Vavoom 1.24 and earlier allows remote attackers to cause a denial of service (daemon crash) via a string with a negative NewLen value within a certain UDP packet that triggers an assertion error.
