The (1) sgetstr and (2) getint functions in Sauerbraten 2006_02_28, as derived from the Cube engine, allow remote attackers to cause a denial of service (segmentation fault) via long streams of input data that trigger an out-of-bounds read, as demonstrated using SV_EXT tag data in the Cube engine, which is not properly handled by getint.

engine/server.cpp in Sauerbraten 2006_02_28, as derived from the Cube engine, allows remote attackers to cause a denial of service (segmentation fault) via a client that does not completely join the game and times out, which results in a null pointer dereference.
