Description OSIDB Bzimport 2026-04-12 13:01:24 UTC 
R 3.4.4 contains a local buffer overflow vulnerability that allows attackers to execute arbitrary code by injecting malicious input into the GUI Preferences language field. Attackers can craft a payload with a 292-byte offset and JMP ESP instruction to execute commands like calc.exe when the payload is pasted into the Language for menus and messages field.
