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.

A local privilege escalation vulnerability exists during the installation of Epic Games Store via the Microsoft Store. A low-privilege user can replace a DLL file during the installation process, which may result in unintended elevation of privileges.

Epic Games Psyonix Rocket League <=1.95 contains an insecure permissions vulnerability that allows authenticated users to modify executable files with full access permissions. Attackers can leverage the 'F' (Full) flag for the 'Authenticated Users' group to change executable files and potentially escalate system privileges.

Epic Games Easy Anti-Cheat 4.0 contains an unquoted service path vulnerability that allows local non-privileged users to execute arbitrary code with elevated system privileges. Attackers can exploit the service configuration by inserting malicious code in the system root path that would execute with LocalSystem privileges during application startup.

Epic Games Launcher Incorrect Default Permissions Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Epic Games Launcher. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

The specific flaw exists within the product installer. The product applies incorrect default permissions to a sensitive folder. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-24329.

A vulnerability classified as problematic was found in Epic Games Launcher up to 17.2.1. This vulnerability affects unknown code in the library profapi.dll of the component Installer. The manipulation leads to untrusted search path. Attacking locally is a requirement. The complexity of an attack is rather high. The exploitation appears to be difficult.

This vulnerability allows local attackers to escalate privileges on affected installations of Epic Games Launcher. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the product installer. The product applies incorrect default permissions to a sensitive folder. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Epic Games Launcher versions prior to 8.2.2. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handler for the com.epicgames.launcher protocol. A crafted URI with the com.epicgames.launcher protocol can trigger execution of a system call composed from a user-supplied string. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-7241.
