Multiple buffer overflows in Doomsday (aka deng) 1.9.0-beta5.1 and earlier allow remote attackers to execute arbitrary code via a long chat (PKT_CHAT) message that is not properly handled by the (1) D_NetPlayerEvent function in d_net.c or the (2) Msg_Write function in net_msg.c, or (3) many commands that are not properly handled by the NetSv_ReadCommands function in d_netsv.c; or (4) cause a denial of service (daemon crash) via a chat (PKT_CHAT) message without a final '\0' character.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
