Objavljena je nadogradnja koja ispravlja nekoliko sigurnosnih propusta u programskom paketu php5. Neki od propusta zlonamjernim korisnicima omogućuju izvođenje DoS napada te izvršavanje proizvoljnog programskog koda.
Paket:
PHP 5.2.x, PHP 5.3.x
Operacijski sustavi:
Debian Linux 5.0 (lenny), Debian Linux 6.0 (squeeze)
Kritičnost:
5.5
Problem:
cjelobrojno prepisivanje, neodgovarajuća provjera ulaznih podataka, pogreška u programskoj funkciji, pogreška u programskoj komponenti
Neki od ispravljenih nedostataka javljaju se zbog cjelobrojnog prepisivanja u radu modula "Exif" i "Calendar", gubitka informacija u radu funkcije "var_export()" te mogućnosti rušenja aplikacije prilikom rada modula "Zip".
Posljedica:
Udaljeni, zlonamjerni korisnici ove nepravilnosti mogu iskoristiti za pokretanje napada uskraćivanja usluge te izvršavanje proizvoljnog programskog koda.
Rješenje:
Svim se korisnicima savjetuje primjena objavljene nadogradnje kako bi uklonili opisane propuste.
