CVE-2018-10403 (GCVE-0-2018-10403)

Vulnerability from cvelistv5 – Published: 2018-06-13 22:00 – Updated: 2024-08-05 07:39

Summary

An issue was discovered in F-Secure XFENCE and Little Flocker. A maliciously crafted Universal/fat binary can evade third-party code signing checks. By not completing full inspection of the Universal/fat binary, the user of the third-party tool will believe that the code is signed by Apple, but the malicious unsigned code will execute.
