Our audit of Homebrew (blog.trailofbits.com)

Article summary

An audit of Homebrew, a package manager for macOS, was conducted to identify potential security vulnerabilities. The audit found several issues, including the ability to load executable code from unexpected sources and undermine the integrity of Homebrew's sandboxing. The issues were not critical but could be exploited by an attacker to compromise the security of Homebrew and its users. The audit was sponsored by the Open Tech Fund as part of its mission to secure critical internet infrastructure.

Main themes

• Homebrew security audit
• Package manager vulnerabilities
• macOS security
• CI/CD security
• Open-source security

What commenters say

• The audit findings were not surprising and are consistent with what would be expected from a similarly sized userspace package manager.
• Homebrew's approach to package management is limited by its need to accommodate programs with hardcoded paths, which can make it difficult to use in certain scenarios.
• Alternative package managers, such as MacPorts and pkgsrc, may offer better security and manageability than Homebrew.
• The use of pre-built binaries can introduce security risks, and source distribution may be a more robust approach to package management.
• Homebrew's popularity can be attributed to its ease of use, simplicity, and large collection of available packages.
• The choice of package manager ultimately depends on individual needs and preferences, and there is no one-size-fits-all solution.
