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.

Sauerbraten 2006_02_28, as derived from the Cube engine, allows remote attackers to cause a denial of service (client exit) by forcing the server to change to a map (ogz) file whose name contains ".." sequences and has a certain length that prevents the addition of the ".ogz" extension.
