This blog post provides details about nine vulnerabilities affecting the IPv6 network protocol stack of EDK II, TianoCore's open source reference implementation of UEFI.

Part 2 of a series about participation in the Pwn2Own Toronto 2023 contest.

In this blog post, we present a new vulnerability on the Gecko Bootloader from Silicon Labs more precisely inside the OTA parser.

This article provides a brief overview of how Microsoft Open Management Infrastructure (OMI) works, as well as two vulnerabilities that the Quarkslab Cloud team identified through fuzzing techniques.

In this blog post we discuss the details of two vulnerabilities we discovered in the Trusted Platform Module (TPM) 2.0 reference implementation code. These two vulnerabilities, an out-of-bounds write (CVE-2023-1017) and an out-of-bounds read (CVE-2023-1018), affected several TPM 2.0 software implementations (such as the ones used by virtualization software) as well as a number of hardware TPMs.

In this blog post we analyze a heap overflow vulnerability we discovered in the IPv6 stack of OpenBSD, more specifically in its slaacd daemon. This issue, whose root cause can be found in the mishandling of Router Advertisement messages containing a DNSSL option with a malformed domain label, was patched by OpenBSD on March 21, 2022. A proof-of-concept to reproduce the vulnerability is provided.

This post is a quick vulnerability report summary for a vulnerability we found while fuzzing the TCP/IP stack CycloneTCP.

In this blog post we analyze a denial of service vulnerability affecting the IPv6 stack of Windows. This issue, whose root cause can be found in the mishandling of IPv6 fragments, was patched by Microsoft in their February 2021 security bulletin.

This blog post provides details about four vulnerabilities we found in the IPv6 stack of FreeBSD, more specifically in rtsold(8), the router solicitation daemon. The bugs affected all supported versions of FreeBSD, and the most severe of them could allow an attacker attached to the same physical link to gain remote code execution as root on vulnerable systems. The vulnerabilities were discovered and reported to FreeBSD Security Team in November 2020. FreeBSD issued fixes for these bugs on December 1st, 2020 along with security advisory FreeBSD-SA-20:32.rtsold.
