Arch Security Team The Arch Security Team is a volunteer group dedicated to improving the security of the Arch Linux distribution and related projects. The team coordinates with upstream projects such as Linux kernel, systemd, Pacman, and GNOME to manage advisories, patches, and disclosure timelines. Known for triaging vulnerabilities reported through channels like CVE and collaborating with organizations including MITRE, Debian, Red Hat, and OpenSSL Project, the group operates alongside distributions such as Ubuntu, Fedora, Gentoo, and Slackware.

History

The team originated as a response to early security incidents affecting Arch Linux in the late 2000s, following practices established by projects like FreeBSD and Debian Security Team. Over time the group adopted disclosure models similar to OpenBSD and guidance from CERT Coordination Center and US-CERT. High-profile coordinated responses involved software such as OpenSSL, glibc, sudo, GnuPG, and OpenSSH, and the team has tracked advisories from vendors like Canonical, Red Hat, SUSE, and Oracle. The evolution of tooling incorporated influences from Git, GitHub, GitLab, Trac, and JIRA for issue tracking and patch management.

Organization and Membership

Membership comprises volunteers drawn from contributors to Arch Linux infrastructure, including developers familiar with Pacman, makepkg, systemd, linux-lts, and AUR (Arch User Repository). The team maintains liaisons with the Arch Linux Security Advisory coordinators, trusted users from AUR Maintainers, and developers of packages like X.Org, Mesa (computer graphics), KDE, and LXQt. Members often have experience with security tools such as OpenVAS, Nmap, Metasploit Framework, Wireshark, and Valgrind, and collaborate with incident response entities like CERT/CC, FIRST members, and distro teams at Debian Project and Arch Linux ARM. Governance aligns with community norms used by Free Software Foundation, Linux Foundation, and Apache Software Foundation.

Responsibilities and Activities

The team monitors public vulnerability feeds including CVE, NVD, OSS-Fuzz, and advisories from vendors like Microsoft, Apple, and Google. Responsibilities include producing security advisories, preparing mitigations for packages such as OpenSSL, LibreSSL, GnuTLS, BIND, PostgreSQL, MySQL, nginx, Apache HTTP Server, PHP, Python (programming language), and Ruby (programming language). Activities encompass backporting patches, coordinating coordinated disclosure with upstream projects like GNOME Project and KDE e.V., and working with cryptographic projects such as OpenPGP and NaCl. The team also audits packaging scripts for systemd, kernel modules like eBPF, and firmware distributed by projects like coreboot and SeaBIOS.

Security Policies and Procedures

Policy development references standards from ISO/IEC 27001 and best practices from OWASP, CIS (Center for Internet Security), and NIST publications like NIST SP 800-53 and NIST Cybersecurity Framework. Procedures cover vulnerability disclosure timelines aligned with CERT/CC coordination, severity scoring using CVSS, and embargo handling consistent with MITRE guidelines. Packaging and repository security draw on models used by Debian Project's security team and Fedora Project's security guidelines. The team enforces cryptographic practices referencing FIPS 140-2 and libraries such as OpenSSL, LibreSSL, and BoringSSL while integrating code-signing workflows similar to GPG use by Debian Project and Red Hat.

Incident Response and Vulnerability Management

Incident response workflow includes triage, replication, patch development, testing in staging mirrors, and public advisory publication coordinated with parties like MITRE, CERT/CC, and FIRST. Vulnerability management tracks CVEs, coordinates with upstream maintainers for packages like systemd, linux-lts, glibc, util-linux, curl, and wget, and stages updates through repositories comparable to Arch User Repository and official repos. The team uses continuous integration practices inspired by Jenkins, CircleCI, and Travis CI for building and regression testing, and applies static analysis tools such as Coverity, Clang Static Analyzer, and cppcheck. Past incidents included responses to vulnerabilities disclosed in projects like OpenSSH, OpenSSL Heartbleed, GnuTLS Heartbleed-related issues, and sudo advisories, with coordination among teams from Debian Security],] Ubuntu Security Team, and Red Hat Product Security.

Community Interaction and Communications

Communication channels include mailing lists modeled on lists.gnu.org patterns, forums like Arch Linux Forums, microblogging interactions on Twitter, and coordination via issue trackers on GitHub and GitLab. The team publishes advisories similar to those from Debian Security Advisory and Red Hat Security Advisories, and engages with security researchers from projects such as OWASP, Mozilla Foundation, Chromium Project, and Google Project Zero. Outreach includes talks at conferences like Defcon, Black Hat, BSides, FOSDEM, LinuxCon, and USENIX Security Symposium, and collaboration with academic groups from institutions like MIT, Stanford University, University of Cambridge, and ETH Zurich to promote secure packaging and disclosure practices.
