Google menambal zero-day Chrome ke-10 yang dieksploitasi di alam liar tahun ini

September 14, 2021 by Winnie the Pooh

Google telah merilis Chrome 93.0.4577.82 untuk Windows, Mac, dan Linux untuk memperbaiki sebelas kerentanan keamanan, dua di antaranya adalah zero-days yang dieksploitasi di alam liar.

“Google menyadari bahwa eksploitasi untuk CVE-2021-30632 dan CVE-2021-30633 ada di alam liar,” perusahaan mengungkapkan dalam catatan rilis untuk versi Chrome baru.

Pembaruan saat ini diluncurkan di seluruh dunia di saluran desktop Stabil, dan Google menyatakan itu akan tersedia untuk semua orang selama beberapa hari ke depan.

Google Chrome juga akan secara otomatis memeriksa pembaruan baru saat Anda memulai ulang browser di lain waktu.

Dua kerentanan zero-day yang diperbaiki hari ini diungkapkan ke Google pada 8 September 2021, dan keduanya merupakan bug memori.

CVE-2021-30632 adalah penulisan di luar batas di mesin JavaScript V8, dan bug CVE-2021-30633 adalah bug use-after-free di API DB yang Diindeks.

Meskipun bug ini sering menyebabkan browser crash, pelaku ancaman terkadang dapat mengeksploitasinya untuk melakukan eksekusi kode jarak jauh, sandbox escapes, dan perilaku berbahaya lainnya.

Sementara Google telah mengungkapkan bahwa kedua bug telah dieksploitasi di alam liar, mereka belum membagikan informasi lebih lanjut mengenai serangan tersebut.

Dengan dua kerentanan ini, Google kini telah menambal total sepuluh kerentanan zero-day di Chrome pada tahun 2021.

Karena kerentanan ini diketahui telah dieksploitasi secara liar, sangat disarankan agar semua Google Chrome segera memperbarui ke versi terbaru.
