Google memperbaiki kerentanan zero-day kedua yang aktif dieksploitasi bulan ini

March 15, 2021 by Winnie the Pooh

Google telah memperbaiki zero-day Chrome yang dieksploitasi secara aktif bulan ini dengan merilis Chrome 89.0.4389.90 ke saluran desktop Stabil untuk pengguna Windows, Mac, dan Linux.

Zero-day yang dilacak sebagai CVE-2021-21193 dinilai oleh Google sebagai kerentanan dengan tingkat keparahan tinggi dan dilaporkan oleh peneliti Anonymous pada hari Selasa.

Google menggambarkannya sebagai “use after free bug in Blink”, mesin rendering browser sumber terbuka yang dikembangkan oleh proyek Chromium dengan kontribusi dari Google, Facebook, Microsoft, dan lainnya.

Eksploitasi zero-day yang berhasil dapat mengakibatkan eksekusi kode arbitrer pada sistem yang menjalankan versi Chrome yang rentan.

Meskipun Google mengatakan bahwa mereka mengetahui CVE-2021-21193 aktif dieksploitasi, Google tidak membagikan info mengenai serangan yang sedang berlangsung ini.

Hingga informasi lebih lanjut tersedia, pengguna Chrome seharusnya memiliki lebih banyak waktu untuk menerapkan pembaruan keamanan yang diluncurkan dalam beberapa hari mendatang untuk mencegah upaya eksploitasi.

Kurangnya info tambahan juga akan mencegah pelaku ancaman lainnya mengembangkan eksploitasi mereka sendiri yang menargetkan zero-day ini.
