What is CVE-2024-42381?
CVE-2024-42381 is a high-severity code injection vulnerability in n/a, published on 31 Jul 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.)
