Real VNC: User-assisted execution of arbitrary code

Real VNC: User-assisted execution of arbitrary code The Real VNC client is vulnerable to execution of arbitrary code when connecting to a malicious server. vnc 2009-03-09 2009-03-09: 01 255225 remote 4.1.3 4.1.3

Real VNC is a remote desktop viewer display system.

An unspecified vulnerability has been discovered int the CMsgReader::readRect() function in the VNC Viewer component, related to the encoding type of RFB protocol data.

A remote attacker could entice a user to connect to a malicious VNC server, or leverage Man-in-the-Middle attacks, to cause the execution of arbitrary code with the privileges of the user running the VNC viewer.

There is no known workaround at this time.

All Real VNC users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/vnc-4.1.3"
