| <p> |
| NoMachine's NX establishes remote connections to X11 desktops over |
| small bandwidth links. NX and NX Node are the compression core |
| libraries, whereas NX is used by FreeNX and NX Node by the binary-only |
| NX servers. |

| <description> |
| <p> |
| Multiple integer overflow and buffer overflow vulnerabilities have been |
| discovered in the X.Org X server as shipped by NX and NX Node |
| (vulnerabilities 1-4 in GLSA 200801-09). |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could exploit these vulnerabilities via unspecified |
| vectors, leading to the execution of arbitrary code with the privileges |
| of the user on the machine running the NX server. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All NX Node users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-misc/nxnode-3.1.0-r2"</code> |
