When compared to applications like TeXShop or TeXmaker, TeXstudio certainly has more fans. Indeed this program contains all of the major features LaTeX users are looking for such as structure view, assistants for formulas, images and tables and many other useful features.
Many researchers have turned to TeXstudio as a free and open source alternative to other programs, most of them proprietary.
This program provides color syntax coding, an integrated PDF viewer, a tree view of document structure and can also auto-complete many of the standard commands LaTeX users may use. Another useful feature that this of course includes is a spell-checker and a thesaurus.
Though TeXstudio isn't necessarily an application built for beginners, it does include wizards and assistance from within the application.
If you want to try something new with many features users have been clamoring for (for quite a while), then TeXstudio is definitely a contender and it's a free and open-source project built by collaborators.
TeXstudio can open LaTeX documents, edit LaTeX documents and highlight syntax.
Features and highlights
- Block cursors
- Auto completion
- Customizable menus, toolbars and shortcuts
- Scripting support
- Direct access to many LaTeX tags and more than 1000 mathematical symbols
- Link overlay

LibreOffice is a powerful office suite; Its clean interface and its powerful tools let you unleash your creativity and grow your productivity. LibreOffice embeds several applications that make it the most powerful Free & Open Source Office suite on the market
A vulnerability in LibreOffice’s Impress Remote Protocol, allows a remote attacker to cause the product to crash, potentially executing arbitrary code by sending the TCP port 1599 (used by the protocol) a malformed request.
In LibreOffice 4.0.0 and later, a new feature was added for remote control capabilities in Impress. Users can run a smart phone application to communicate with Impress over a custom protocol to switch slides and the like. By default whenever Impress is started, it immediately begins listening on TCP port 1599 on all interfaces.
The protocol used by Impress is currently very simple and is described here:
Impress Remote Protocol
A simple initial handshake message sent by clients looks like:
The message is terminated with a blank line. Encoded, the above message looks like:
“LO_SERVER_CLIENT_PAIRnclient namenclient PINnn”
The source code responsible for handling these requests is in:
The vulnerability lies in the line:
If readLine returns 0, then the pSocket is freed, but execution does not stop there. Most likely what was intended is:
However, pSocket continues to be used for the rest of this while loop iteration. pSocket is used in a few places, but most interestingly, during the inner do…while loop when the remaining portion of content is read in. If the freed memory can be overwritten sometime before or during these later readLine calls, then either the readLine vptr can be hijacked, or the buffer counters stored within pSocket can be messed with to generate a subsequent overflow or something similar.
We can easily supply data to this socket while still causing readLine to return 0 on vulnerable line of code. Looking at the readLine implementation in BufferedStreamSocket.css, input is capped at 20000 bytes. (MAX_LINE_LENGTH is the key check we’re targeting.)
So for this first request, we want to send a very long PIN, since that is what is being read in on the vulnerable line of code.
A one liner like this will cause a reliable crash of Impress and the rest of LibreOffice:
python -c 'print('LO_SERVER_CLIENT_PAIRnMYNAMEn'+('A'*20000)+'nn')' nc 127.0.0.1 1599
Workaround: Disable Impress Remote
While the remote control service is enabled by default, it can be disabled easily through the following menus:
Open LibreOffice, go to 'Tools -> Options...'
Select 'LibreOffice Impress -> General'
Uncheck 'Presentation -> Enable remote control'
