Apple memperbaiki zero-day baru yang digunakan dalam serangan terhadap iPhone, iPad

October 25, 2022 by Eevee

Apple telah mengatasi kerentanan zero-day kesembilan yang dieksploitasi dalam serangan di alam liar sejak awal tahun.

Apple mengungkapkan bahwa mereka mengetahui laporan yang mengatakan kelemahan keamanan “mungkin telah dieksploitasi secara aktif.”

Bug (CVE-2022-42827) adalah masalah out-of-bounds write yang dilaporkan ke Apple oleh peneliti anonim dan disebabkan oleh perangkat lunak yang menulis data di luar batas buffer memori saat ini.

Hal ini dapat mengakibatkan kerusakan data, aplikasi mogok, atau eksekusi kode karena hasil yang tidak ditentukan atau tidak diharapkan (juga dikenal sebagai kerusakan memori) yang dihasilkan dari data berikutnya yang ditulis ke buffer.

Seperti yang dijelaskan Apple, jika berhasil dieksploitasi dalam serangan, zero-day ini dapat digunakan oleh penyerang potensial untuk mengeksekusi kode arbitrer dengan hak istimewa kernel.

Daftar lengkap perangkat yang terpengaruh termasuk iPhone 8 dan versi lebih baru, iPad Pro (semua model), iPad Air generasi ke-3 dan versi lebih baru, iPad generasi ke-5 dan versi lebih baru, serta iPad mini generasi ke-5 dan versi lebih baru.

Apple mengatasi kerentanan zero-day di iOS 16.1 dan iPadOS 16 dengan pemeriksaan batas yang ditingkatkan.

Sementara Apple telah mengungkapkan bahwa mereka mengetahui laporan eksploitasi aktif dari kerentanan ini di alam liar, itu belum merilis informasi apa pun mengenai serangan ini.

Ini kemungkinan akan memungkinkan pelanggan Apple untuk menambal perangkat mereka sebelum lebih banyak penyerang mengembangkan eksploitasi tambahan dan mulai menggunakannya dalam serangan yang menargetkan iPhone dan iPad yang rentan.

Meskipun bug zero-day ini kemungkinan besar hanya digunakan dalam serangan yang sangat bertarget, menginstal pembaruan keamanan hari ini sangat disarankan untuk memblokir upaya serangan apa pun.
