Dua anak menemukan bug screensaver di Linux Mint

January 19, 2021 by Winnie the Pooh

Pengelola proyek Linux Mint telah mengatasi bug keamanan yang memungkinkan penyerang melewati screensaver OS.

Aspek aneh dari kerentanan ini terkait dengan penemuannya, pada kenyataannya, ditemukan oleh dua anak yang bermain di komputer ayah mereka.

Pengembang utama Linux Mint Clement Lefebvre mengonfirmasi bahwa bug berada di libcaribou, komponen keyboard layar (OSK) yang merupakan bagian dari lingkungan desktop Cinnamon yang digunakan oleh Linux Mint.

“Kami kemungkinan besar akan menambal libcaribou di sini,” tulis Lefebvre. “Kami memiliki dua masalah berbeda:

  • Di semua versi Cinnamon, keyboard di layar (diluncurkan dari menu) berjalan dalam proses Cinnamon dan menggunakan libcaribou. Menekan ē membuat Cinnamon crash.
  • Di versi Cinnamon 4.2 dan lebih tinggi, ada libcaribou OSK di screensaver. Menekan ē di sana akan merusak screensaver

Kerentanan ini dipicu saat pengguna menekan tombol “ē” pada keyboard di layar, ini menyebabkan crash pada proses desktop Cinnamon. Jika keyboard di layar dibuka dari screensaver, bug merusak screensaver sehingga pengguna dapat mengakses desktop.

Masalah ini diperkenalkan di Linux Mint OS sejak pembaruan Xorg untuk memperbaiki CVE-2020-25712 heap-buffer overflow pada bulan Oktober. Bug mempengaruhi semua distribusi yang menjalankan Cinnamon 4.2+ dan perangkat lunak apa pun yang menggunakan libcaribou.

Kerentanan telah diatasi dengan rilis tambalan untuk Mint 19.x, Mint 20.x, dan LMDE 4.
