Typing the special four-character string "::" into certain iOS search bars causes apps to crash, highlighting vulnerabilities in Apple's SpringBoard application management.
Notably, using the string in the Settings and Notes apps leads to an application crash, forcing users back to the home screen. Tests by El Reg confirmed this behavior.
Unlike previous severe text-related vulnerabilities, this bug is benign and cannot be exploited for malicious purposes, meaning it's not a serious security threat for users.
Researcher Patrick Wardle discovered the technical reasons behind the crash but reassured that this bug poses no risk of exploitation, unlike past problematic bugs.
