Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
NX uses code from the X.org X11 server which is prone to multiple |
| 19 |
vulnerabilities. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
NoMachine's NX establishes remote connections to X11 desktops over |
| 25 |
small bandwidth links. NX and NX Node are the compression core |
| 26 |
libraries, whereas NX is used by FreeNX and NX Node by the binary-only |
| 27 |
NX servers. |

Description |
| 42 |
=========== |
| 43 |
|
| 44 |
Multiple integer overflow and buffer overflow vulnerabilities have been |
| 45 |
discovered in the X.Org X server as shipped by NX and NX Node (GLSA |
| 46 |
200806-07). |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
A remote attacker could exploit these vulnerabilities via unspecified |
| 52 |
vectors, leading to the execution of arbitrary code with the privileges |
| 53 |
of the user on the machine running the NX server. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All NX Node users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot --verbose ">=net-misc/nxnode-3.2.0-r3" |
| 67 |
|
| 68 |
All NX users should upgrade to the latest version: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=net-misc/nx-3.2.0-r2" |
| 72 |
