A security weakness has been discovered in LINE for Windows that allows for DLL hijacking due to the improper loading of Msftedit.dll via a relative path. This vulnerability occurs when the application fails to enforce a secure DLL search path, allowing an attacker to place a malicious DLL in the installation directory. When the application is executed, it may inadvertently load the compromised DLL instead of the legitimate version from the System32 directory, potentially leading to unauthorized actions on the system.
