What is CVE-2018-0518?

The LINE messaging application for iOS versions 7.1.3 to 7.1.5 exhibits a flaw where it fails to properly verify X.509 certificates from SSL servers. This oversight enables attackers to execute man-in-the-middle attacks, potentially leading to the spoofing of legitimate servers. As a result, sensitive information transmitted through the app can be intercepted, jeopardizing user privacy and data security.
