[ GLSA 200807-07 ] NX: User-assisted execution of arbitrary code

[GLSA]

Gentoo Linux Security Advisory

Title: NX: User-assisted execution of arbitrary code (GLSA 200807-07)
Severity: normal
Exploitable: remote
Date: July 09, 2008
Bug(s): #230147
ID: 200807-07

Synopsis


NX uses code from the X.org X11 server which is prone to multiple
vulnerabilities.


Background


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.


Affected Packages

Package: net-misc/nxnode
Vulnerable: < 3.2.0-r3
Unaffected: >= 3.2.0-r3
Architectures: All supported architectures

Package: net-misc/nx
Vulnerable: < 3.2.0-r2
Unaffected: >= 3.2.0-r2
Architectures: All supported architectures


Description


Multiple integer overflow and buffer overflow vulnerabilities have been
discovered in the X.Org X server as shipped by NX and NX Node (GLSA
200806-07).


Impact


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.


Workaround


There is no known workaround at this time.


Resolution


All NX Node users should upgrade to the latest version:
