U radu programskog paketa php-eaccelerator uočena su dva nova sigurnosna propusta. Udaljeni ih napadač može iskoristiti za napad uskraćivanjem usluga (DoS) te čitanje proizvoljnih podataka.
Paket:
php-eaccelerator 0.x
Operacijski sustavi:
Fedora 15
Kritičnost:
6.4
Problem:
cjelobrojno prepisivanje, neodgovarajuća provjera ulaznih podataka
Sigurnosne ranjivosti se javljaju zbog pogrešnog izračunavanja hash vrijednosti iz ulaznih parametara te zbog cjelobrojnog prepisivanja u funkciji "exif_process_IFD_TAG".
Posljedica:
Udaljeni napadač navedene ranjivosti može iskoristiti za pregled sadržaja proizvoljnih memorijskih lokacija te DoS (eng. Denial of Service) napad.
Rješenje:
Rješenje problema sigurnosti je nadogradnja na novije inačice.
