Apple security updates

Apple delivered on a promise made last week to publish updates for a bug that crashed Mac and iOS applications that included the " జ్ఞ‌ా " Indian Telugu character.

The Cupertino-based company released today a supplemental update for macOS High Sierra 10.13.3, and new versions for iOS (11.2.6), tvOS (11.2.6), and watchOS (4.2.3) to address the issue.

Apple tracks the bug as CVE-2018-4124, and describes it as "a memory corruption issue." It says it addressed the bug "through improved input validation."

Users are advised to apply the update if they want to surf the Internet these days safely.

The bug came to light last week and caused quite a frenzy on social media. The problematic Telugu character quickly became every Android users' favorite character, with people adding it in their social media profile names, just to crash their friends' iPhones.

The Telugu character's use grew so rampant on Twitter that the social network's staff banned it from use for the time being.

Manish Goregaokar, a security engineer for the Mozilla Foundation, wrote a blog post last week explaining why Mac and iOS apps were crashing because of this Unicode character.

Applying the updates below should keep most users' devices safe and crash-free.
