U programskom paketu OpenSSL otkriveno je nekoliko sigurnosnih nedostataka koji se mogu iskoristiti za neovlašten pristup i otkrivanje osjetljivih podataka.
Paket:
Operacijski sustavi:
HP-UX 11.x
Kritičnost:
9.3
Problem:
neodgovarajuće rukovanje memorijom, pogreška u programskoj komponenti
Sigurnosni propusti otkriveni su u implementaciji protokola DTLS i SSL, u komponentama SGC (Server Gated Cryptography) i ECDH, te u neodgovarajućem rukovanju memorijom gdje dolazi do dvostrukog oslobađanja memorije.
Posljedica:
Zlonamjerni napadač može iskoristiti navedene nedostatke za čitanje osjetljivih informacija i neovlašten pristup.
Rješenje:
Izdana je nadogradnja koja otklanja opisane propuste pa se korisnicima savjetuje njena primjena.
