Buffer overflow in Unreal Tournament 3 1.3beta4 and earlier allows remote attackers to cause a denial of service (memory corruption and daemon crash) or possibly execute arbitrary code via a UDP packet containing a large value in a certain size field, followed by a data string of that size, aka attack 1 in ut3mendo.c.

Unreal Tournament 3 1.3beta4 and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a UDP packet in which the value of a certain size field is greater than the total packet length, aka attack 2 in ut3mendo.c.

Directory traversal vulnerability in ImageServer (aka UTImageServer) in WebAdmin before 1.7 for Epic Games Unreal Tournament 3 (UT3) 1.3 allows remote attackers to read arbitrary files via a .. (dot dot) in the URI.
