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.

Epic Games / Psyonix Rocket League <=1.95 is affected by Buffer Overflow. Stack-based buffer overflow occurs when Rocket League handles UPK object files that can result in code execution and denial of service scenario.

psyonix

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.

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.
