NX uses code from the X.org X11 server which is prone to multiple vulnerabilities.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| net-misc/nx | * | < 3.2.0-r2 | >= 3.2.0-r2 |
| net-misc/nxnode | * | < 3.2.0-r3 | >= 3.2.0-r3 |
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.
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).
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.
There is no known workaround at this time.
All NX Node users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/nxnode-3.2.0-r3"
All NX users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/nx-3.2.0-r2"

NX in the 2.1 series uses XFree86 4.3 code which is prone to an integer overflow vulnerability.

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.
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.
There is no known workaround at this time.
