<title>NX 2.1: User-assisted execution of arbitrary code</title>
|
|
<synopsis>
|
|

|
|
overflow vulnerability.

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.

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

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

<workaround>

There is no known workaround at this time.

All NX users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/nx-3.0.0"</code>
|
|
<p>
|
|
All NX Node users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/nxnode-3.0.0-r3"</code>
