U radu programskog paketa php_eaccelerator otkriveno je nekoliko nedostataka. Otkrivene propuste mogu iskoristiti udaljeni napadači kako bi izveli DoS napad, otkrili informacije o lozinkama, dodavali i mijenjali proizvoljne datoteke te izvršavali proizvoljni programski kod.
Najopasniji nedostaci su otkriveni u funkciji "socket_connect" u datoteci "ext/sockets/sockets.c" i u funkcijama koje pozivaju funkcije malloc, calloc i realloc.
Posljedica:
Opisane nedostatke može iskoristiti udaljeni napadač kako bi izveo DoS napad. Ostali nedostaci se mogu iskoristiti za otkrivanje zaporki, proizvoljno izvršavanje programskog koda te dodavanje i izmjenu proizvoljnih datoteka.
Rješenje:
Informacije o ostalim nedostacima mogu se naći u izvornoj preporuci. Svim korisnicima se savjetuje korištenje dostupne nadogradnje.
