U radu programskog paketa OpenSSL, za sustave Fedora 15 i 16, uočene su dvije sigurnosne ranjivosti. Napadačima omogućuju zaobilaženje sigurnosnih ograničenja i izvođenje DoS napada.
| Paket: | OpenSSL 1.x |
| Operacijski sustavi: | Fedora 15, Fedora 16 |
| Kritičnost: | 4.4 |
| Problem: | pogreška u programskoj funkciji, pogreška u programskoj komponenti |
| Iskorištavanje: | udaljeno |
| Posljedica: | uskraćivanje usluga (DoS), zaobilaženje postavljenih ograničenja |
| Rješenje: | programska zakrpa proizvođača |
| CVE: | CVE-2012-0884, CVE-2012-1165 |
| Izvorni ID preporuke: | FEDORA-2012-4659 |
| Izvor: | Fedora |
| Problem: | |
| Ranjivosti su posljedica pogrešaka u CMS i PKCS #7 dekripcijskom kodu, te greške u funkciji "mime_param_cmp()". |
|
| Posljedica: | |
| Napadač ih može iskoristiti za zaobilaženje postavljenih ograničenja i izvođenje DoS napada. |
|
| Rješenje: | |
| Korisnicima se preporuča korištenje nadogradnje. |
