What is CVE-2018-10470?
CVE-2018-10470 is a medium-severity vulnerability in Objective Development Software GmbH Little Snitch, published on 12 Jun 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Little Snitch versions 4.0 to 4.0.6 use the SecStaticCodeCheckValidityWithErrors() function without the kSecCSCheckAllArchitectures flag and therefore do not validate all architectures stored in a fat binary. An attacker can maliciously craft a fat binary containing multiple architectures that may cause a situation where Little Snitch treats the running process as having no code signature at all while erroneously indicating that the binary on disk does have a valid code signature. This could lead to users being confused about whether or not the code signature is valid.
