+Subject: [PATCH] slirp: use correct size while emulating IRC commands
+
+While emulating IRC DCC commands, tcp_emu() uses 'mbuf' size
+'m->m_size' to write DCC commands via snprintf(3). This may
+lead to OOB write access, because 'bptr' points somewhere in
+the middle of 'mbuf' buffer, not at the start. Use M_FREEROOM(m)
+size to avoid OOB access.

+with completion and history.
+
+@item Can edit files of hundreds of Megabytes without being slow by
+using a highly optimized internal representation and by mmaping the

+
+@item Full Unicode support, including multi charset handling (8859-x,
+UTF8, SJIS, EUC-JP, ...) and bidirectional editing respecting the
+Unicode bidi algorithm.  Arabic and Indic scripts handling (in
+progress).
+
+@item WYSIWYG HTML/XML/CSS2 mode graphical editing.  Also supports
+Lynx like rendering on VT100 terminals.
+
+@item WYSIWYG DocBook mode based on XML/CSS2 renderer.
+
+@item C mode: coloring with immediate update.  Emacs like auto-indent.
+
+@item Shell mode: colorized VT100 emulation so that your shell work
+exactly as you expect.  Compile mode with next/prev error.
+
+@item Input methods for most languages, including Chinese (input
+methods come from the Yudit editor).
+
+@item Hexadecimal editing mode with insertion and block commands.
+Unicode hexa editing is also supported.

+@item Works on any VT100 terminals without termcap.  UTF8 VT100
+support included with double width glyphs.
