NX: User-assisted execution of arbitrary code

NX: User-assisted execution of arbitrary code NX uses code from the X.org X11 server which is prone to multiple vulnerabilities. nx, nxnode 2008-07-09 2008-07-09: 01 230147 remote 3.2.0-r3 3.2.0-r3 3.2.0-r2 3.2.0-r2

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"
