| 15 | Synopsis |
| 16 | ======== |
| 17 | |
| 18 | The Network Audio System is vulnerable to a buffer overflow that could |
| 19 | result in the execution of arbitrary code with root privileges. |
| 20 | |
| 21 | Background |
| 22 | ========== |
| 23 | |
| 24 | NAS is a network transparent, client/server audio transport system. |
| 25 | |
| 26 | Affected packages |
| 27 | ================= |
| 28 | |
| 29 | ------------------------------------------------------------------- |
| 30 | Package / Vulnerable / Unaffected |
| 31 | ------------------------------------------------------------------- |
| 32 | 1 media-libs/nas < 1.8b >= 1.8b |
| 33 | |
| 34 | Description |
| 35 | =========== |
| 36 | |
| 37 | Luigi Auriemma has discovered multiple vulnerabilities in NAS, some of |
| 38 | which include a buffer overflow in the function accept_att_local(), an |
| 39 | integer overflow in the function ProcAuWriteElement(), and a null |
| 40 | pointer error in the function ReadRequestFromClient(). |
| 41 | |
| 42 | Impact |
| 43 | ====== |
| 44 | |
| 45 | An attacker having access to the NAS daemon could send an overly long |
| 46 | slave name to the server, leading to the execution of arbitrary code |
| 47 | with root privileges. A remote attacker could also send a specially |
| 48 | crafted packet containing an invalid client ID, which would crash the |
| 49 | server and result in a Denial of Service. |
| 50 | |
| 51 | Workaround |
| 52 | ========== |
| 53 | |
| 54 | There is no known workaround at this time. |
| 55 | |
| 56 | Resolution |
| 57 | ========== |
| 58 | |
| 59 | All NAS users should upgrade to the latest version: |
| 60 | |
| 61 | # emerge --sync |
| 62 | # emerge --ask --oneshot --verbose ">=media-libs/nas-1.8b" |
