<title>NX 2.1: User-assisted execution of arbitrary code</title> |
22 |
<synopsis> |
23 |
NX in the 2.1 series uses XFree86 4.3 code which is prone to an integer |
24 |
overflow vulnerability. |

NoMachine's NX establishes remote connections to X11 desktops over |
44 |
small bandwidth links. NX and NX Node are the compression core |
45 |
libraries, whereas NX is used by FreeNX and NX Node by the binary-only |
46 |
NX servers. |

51 |
Chris Evans reported an integer overflow within the FreeType PCF font |
52 |
file parser (CVE-2006-1861). NX and NX Node are vulnerable to this due |
53 |
to shipping XFree86 4.3.0, which includes the vulnerable FreeType code. |
54 |

<impact type="normal"> |
57 |
<p> |
58 |
A remote attacker could exploit these integer overflows by enticing a |
59 |
user to load a specially crafted PCF font file which might lead to the |
60 |
execution of arbitrary code with the privileges of the user on the |
61 |
machine running the NX server. |
62 |
</p> |
63 |
</impact> |

<workaround> |
65 |
<p> |
66 |
There is no known workaround at this time. |

All NX users should upgrade to the latest version: |
72 |
</p> |
73 |
<code> |
74 |
# emerge --sync |
75 |
# emerge --ask --oneshot --verbose ">=net-misc/nx-3.0.0"</code> |
76 |
<p> |
77 |
All NX Node users should upgrade to the latest version: |
78 |
</p> |
79 |
<code> |
80 |
# emerge --sync |
81 |
# emerge --ask --oneshot --verbose ">=net-misc/nxnode-3.0.0-r3"</code> |
