What is CVE-2018-10470?

Little Snitch versions 4.0 to 4.0.6 exhibit a vulnerability due to the improper use of the SecStaticCodeCheckValidityWithErrors() function, which fails to validate all architectures in fat binaries. Consequently, this oversight allows an attacker to craft a malicious fat binary with multiple architectures, leading Little Snitch to mistakenly classify the running process as lacking a code signature while indicating a valid signature on disk. This inconsistency can mislead users regarding the authenticity of the code signature.
