U radu programskog paketa Chromium uočeni su i ispravljeni brojni sigurnosni propusti. Udaljeni napadači su ih mogli iskoristiti za izvršavanje proizvoljnog programskog koda i DoS (eng. Denial of Service) napad.
Paket:
chromium 11.x
Operacijski sustavi:
Gentoo Linux
Kritičnost:
10
Problem:
neodgovarajuće rukovanje datotekama, neodgovarajuće rukovanje memorijom, pogreška u programskoj komponenti
Uočene su greške u implementaciji komponenti "browser/profiles/profile_impl_io_data.cc", "regex", dodatku "Autofill", neodgovarajuće rukovanje slobodnom memorijom, neodgovarajuće rukovanje datotekama koje sadrže grafičke simbole (eng. glyph) i tibetanski tekst.
Posljedica:
Zlonamjerni napadači mogu iskoristiti nedostatke za pokretanje proizvoljnog programskog koda i napad uskraćivanjem usluga (DoS).
Rješenje:
Kao rješenje problema sigurnosti savjetuje se primjena programskih zakrpi i rješenja proizvođača.
