Several reports emerged last week that Apple devices had problems rendering two characters in the Indian Telugu language.
The problem was quickly exploited on social media as users inserted the characters into profiles and messages, knowing any Apple device user that stumbled across them would see their machines crash.
Apple fixed both its desktop and mobile operating systems today to close the bug, which has been officially codenamed CVE-2018-4124.
Apple said in release notes for both updates that they addressed a problem where “processing a maliciously crafted string may lead to heap corruption”.
TheVerge reported that “all current betas of iOS, macOS, tvOS, and watchOS also fix the crashing problem.”
