Detalji

Kod programskog paketa Maninadrive, namijenjenog operacijskom sustavu Fedora 15, uočeno je nekoliko sigurnosnih propusta. Riječ je o računalnoj igrici za sudjelovanje u utrkama automobila. Propusti nastaju zbog ranjivosti u datotekama "phar_object.c" i "exif.c", pojave cjelobrojnog prepisivanja kod "ext/shmop/shmop.c" te prilikom obrade "ZIPARCHIVE::FL_UNCHANGED" argumenata "_zip_name_locate" funkcije. Uspješna zloupotreba sigurnosnih ranjivosti se manifestira mogućnostima izvođenja napada uskraćivanjem usluga, pokretanjem proizvoljnog programskog koda i pristupom osjetljivim informacijama. Korisnicima ranjivog paketa se savjetuje pravovremena instalacija dostupne nadogradnje.
