U radu programskog paketa Xen uočeno je više sigurnosnih nedostataka. Lokalni ih napadači mogu iskoristiti za dobivanje većih ovlasti i izvođenje napada uskraćivanjem usluge.
| Paket: | xen 4.x |
| Operacijski sustavi: | openSUSE 11.4, openSUSE 12.1 |
| Kritičnost: | 6.3 |
| Problem: | pogreška u programskoj komponenti |
| Iskorištavanje: | lokalno |
| Posljedica: | dobivanje većih privilegija, uskraćivanje usluga (DoS) |
| Rješenje: | programska zakrpa proizvođača |
| CVE: | CVE-2012-2625, CVE-2012-3432, CVE-2012-3433, CVE-2012-3494, CVE-2012-3496, CVE-2012-3515, CVE-2012-3495, CVE-2012-3498 |
| Izvorni ID preporuke: | openSUSE-SU-2012:1174-1 |
| Izvor: | SUSE |
| Problem: | |
| Nedostaci su posljedica pogreške u komponenti PyGrub, neodgovarajućeg rukovanja određenim podacima MMIO operacija, itd. Za uvid u sve propuste preporuča se čitanje izvorne preporuke. |
|
| Posljedica: | |
| Zlonamjernim korisnicima omogućuju izvođenje DoS (eng. Denial of Service) napada i povećanje ovlasti na ranjivom sustavu. |
|
| Rješenje: | |
| Svim se korisnicima savjetuje instalacija odgovarajućih ispravki. |
