Stack-based buffer overflow in LexRuby.cxx (SciLexer.dll) in Scintilla 1.73, as used by notepad++ 4.1.1 and earlier, allows user-assisted remote attackers to execute arbitrary code via certain Ruby (.rb) files with long lines. NOTE: this was originally reported as a vulnerability in notepad++.

SciLexer.dll in Scintilla in Notepad++ (x64) before 7.7 allows remote code execution or denial of service via Unicode characters in a crafted .ml file.
