Reverse Engineering And Exploiting Font Rasterizers The Opentype Saga Presented By Mateusz Jurczy

44CON Talk: Reverse Engineering And Exploiting Font Rasterizers - The OpenType Saga From 44CON ...

44CON Talk: Reverse Engineering And Exploiting Font Rasterizers - The OpenType Saga From 44CON ... Explore the intricacies of font rasterization security in this 57 minute conference talk presented by mateusz jurczy at the 44con information security conference. delve into the world of font file formats, with a focus on opentype, and discover why they are prime targets for attackers. Over the course of the last few months, we performed a detailed security audit of the implementation of opentype font handling present in popular libraries, client side applications and operating systems, which appears to have received much less attention in comparison to e.g. truetype.

44CON London 2015 - Reverse Engineering And Exploiting Font Rasterizers: The OpenType Saga | PPT 44 con 2016 44 con 2014. Reverse engineering and exploiting font rasterizers the opentype saga mateusz “j00ru” jurczyk 44con 2015, london ps> whoami • project zero. In this presentation, we will disclose the details of the 2 vulnerabilities we used to take down 64 bit ie in pwn2own 2015 for the first time. we will go through the poc exploit to demonstrate the techniques we used to work out a working ie 64 bit exploit. A stack based buffer overflow vulnerability was discovered in freetype's cff rasterizer during fuzz testing. the vulnerability occurs when building the hintmap data structure in the cf2 hintmap build function.

First program to properly rasterize type 1 fonts on screen. not commonly adopted world wide, partially due to the advent of opentype. only 30 commercial and 8 free mm fonts released (mostly by adobe itself). very sparse software support nowadays; however, at least microsoft windows (gdi) and adobe reader still support it. Our second round selection of talks this year are: you can find the abstracts for all these talks here. our second round selection of workshops are: you can find more details about these workshops here. tickets for 44con london 2015 are available from our shop. Fontdue is a simple, no std (does not use the standard library for portability), pure rust, truetype (.ttf/.ttc) & opentype (.otf) font rasterizer and layout tool. it strives to make interacting with fonts as fast as possible, and currently has the lowest end to end latency for a font rasterizer. Infocon.org is an archive of hacking and security conference videos, documentaries, rainbow tables, word lists and podcasts.
