Epic GamesCVEs & Vulnerabilities
16 CVEs affecting Epic Games products, tracked from the National Vulnerability Database, with CVSS/EPSS scores and exploitation status.
Most Affected Products
Unreal engine 3, as used in Unreal Tournament 3 1.3, Frontlines: Fuel of War 1.1.1, and other products, allows remote attackers to cause a denial of service (server exit) via a packet with a large length value that triggers a memory allocation failure.
The Unreal engine, as used in Unreal Tournament 3 1.3, Unreal Tournament 2003 and 2004, Dead Man's Hand, Pariah, WarPath, Postal2, and Shadow Ops, allows remote authenticated users to cause a denial of service (server exit) via multiple file downloads from the server, which triggers an assertion failure when the Closing flag in UnChan.cpp is set.
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.
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.
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 2004 (UT2004) 3369 and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a certain sequence of malformed packets.
The UCC dedicated server for the Unreal engine, possibly 2003 and 2004, on Windows allows remote attackers to cause a denial of service (continuous beep and server slowdown) via a string containing many 0x07 characters in (1) a request to the images/ directory, (2) the Content-Type field, (3) a HEAD request, and possibly other unspecified vectors.
Stack-based buffer overflow in the logging function in the Unreal engine, possibly 2003 and 2004, as used in the internal web server, allows remote attackers to cause a denial of service (application crash) via a request for a long .gif filename in the images/ directory, related to conversion from Unicode to ASCII.
Format string vulnerability in games using the Epic Games Unreal Engine 436 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in class names.
Directory traversal vulnerability in manifest.ini in Unreal engine allows remote attackers to overwrite arbitrary files via .. (dot dot) sequences in a UMOD (Unreal MOD) file.
The Unreal Engine, as used in DeusEx 1.112fm and earlier, Devastation 390 and earlier, Mobile Forces 20000 and earlier, Nerf Arena Blast 1.2 and earlier, Postal 2 1337 and earlier, Rune 107 and earlier, Tactical Ops 3.4.0 and earlier, Unreal 1 226f and earlier, Unreal II XMP 7710 and earlier, Unreal Tournament 451b and earlier, Unreal Tournament 2003 2225 and earlier, Unreal Tournament 2004 before 3236, Wheel of Time 333b and earlier, and X-com Enforcer, allows remote attackers to execute arbitrary code via a UDP packet containing a secure query with a long value, which overwrites memory.
Epic Games Unreal Engine 226f through 436 allows remote attackers to cause a denial of service (CPU consumption or crash) and possibly execute arbitrary code via (1) a packet with a negative size value, which is treated as a large positive number during memory allocation, or (2) a negative size value in a package file.
Epic Games Unreal Engine 226f through 436 does not validate the challenge key, which allows remote attackers to exhaust the player limit by joining the game multiple times.
Buffer overflow in Epic Games Unreal Engine 226f through 436 allows remote attackers to cause a denial of service (crash) via a long host string in the Unreal URL.
Directory traversal vulnerability in Unreal Tournament Server 436 and earlier allows remote attackers to access known files via a ".." (dot dot) in an unreal:// URL.
Unreal Tournament 2003 (ut2003) clients and servers allow remote attackers to cause a denial of service via malformed messages containing a small number of characters to UDP ports 7778 or 10777.
