CVE-2024-42381: Homebrew Brew

High severity, CVSS 8.3. EPSS: 0.6% chance of exploitation in the next 30 days.

os/linux/elf.rb in Homebrew brew before 4.2.20 uses ldd to load ELF files obtained from untrusted sources, which allows attackers to achieve code execution via an ELF file with a custom .interp section. NOTE: this code execution would occur during an un-sandboxed binary relocation phase, which occurs before a user would expect execution of downloaded package content. (237d1e783f7ee261beaba7d3f6bde22da7148b0a was the tested vulnerable version.)

Affected products

• Homebrew Brew: before 4.2.20 (fixed in 4.2.20)
