Last modified

CVE-2024-42381 is a high-severity vulnerability rated 8.3/10 on the CVSS scale. 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. EPSS estimates a 0.61% chance of exploitation in the next 30 days.
