Description
R i386 3.5.0 contains a local buffer overflow vulnerability in the GUI Preferences dialog that allows local attackers to trigger a structured exception handler (SEH) overwrite by supplying malicious input. Attackers can craft a payload string in the 'Language for menus and messages' field to overwrite SEH records and achieve code execution with calculator or arbitrary shellcode.
