Pembaruan darurat Google Chrome memperbaiki hari nol ke-9 dalam setahun

December 4, 2022 by Søren

Google telah merilis Chrome 108.0.5359.94/.95 untuk pengguna Windows, Mac, dan Linux untuk mengatasi satu kelemahan keamanan tingkat tinggi, Chrome zero-day kesembilan yang dieksploitasi secara liar sejak awal tahun.

“Google mengetahui laporan bahwa eksploit untuk CVE-2022-4262 ada di alam liar,” kata raksasa pencarian itu dalam penasehat keamanan yang diterbitkan pada hari Jumat.

Menurut Google, versi baru telah mulai diluncurkan ke pengguna di saluran Stable Desktop, dan akan menjangkau seluruh basis pengguna dalam hitungan hari atau minggu.

Pembaruan ini segera diluncurkan ke sistem kami saat BleepingComputer memeriksa pembaruan baru dari menu Chrome > Bantuan > Tentang Google Chrome.

Browser web juga akan secara otomatis memeriksa pembaruan baru dan akan menginstalnya tanpa memerlukan interaksi pengguna setelah peluncuran berikutnya.

Kerentanan zero-day (CVE-2022-4262) disebabkan oleh kelemahan kebingungan tipe tingkat keparahan tinggi di mesin JavaScript Chrome V8 yang dilaporkan oleh Clement Lecigne dari Grup Analisis Ancaman Google.

Meskipun kelemahan keamanan kebingungan jenis umumnya menyebabkan browser mogok setelah berhasil dieksploitasi dengan membaca atau menulis memori di luar batas buffer, pelaku ancaman juga dapat mengeksploitasinya untuk eksekusi kode arbitrer.

Meskipun Google mengatakan mendeteksi serangan yang mengeksploitasi zero-day ini, perusahaan belum membagikan detail teknis atau informasi terkait insiden ini.

“Akses ke detail bug dan tautan dapat dibatasi sampai mayoritas pengguna diperbarui dengan perbaikan,” tambah Google.

“Kami juga akan mempertahankan batasan jika bug ada di perpustakaan pihak ketiga yang juga bergantung pada proyek lain, tetapi belum diperbaiki.”
