.:: Vulnerability Research ::.

In addition to discovering security issues and design flaws in properitary software for our clients, Z-Labs occasionally conducts its own vulnerability research on chosen open source software and performs other security research related activities.

:: Discovery of CVE-2017-17858 vulnerability - multiple memory corruptions during pdf processing

Software affected: MuPDF (ver. 1.12.0)
Advisory: MZET-ADV-2017-01

:: Discovery of CVE-2015-3146 vulnerability - DoS condition (server-side NULL pointer dereference)

:: Security challenges and CTF-like competitions writeups

To constantly improve in the art of vulnerability discovery and to stay sharp with latest exploitation techniques we solve them a lot. We publish our solutions of selected problems at github.

.:: Security tools & Exploits ::.

At Z-Labs a lot of code is written: PoC exploits, custom fuzzers and other custom-written scripts. We release some of them to share with the community.
