GENTOO LINUX SECURITY ANNOUNCEMENT 200302-15
- - ---------------------------------------------------------------------
PACKAGE : tightvnc
SUMMARY : insecure cookie generation
DATE : 2003-02-24 11:34 UTC
EXPLOIT : remote
VERSIONS AFFECTED : <1.2.8
FIXED VERSION : 1.2.8
- - ---------------------------------------------------------------------
- From Red Hat Security Advisory RHSA-2003:041-12:
"The VNC server acts as an X server, but the script for starting it
generates an MIT X cookie (which is used for X authentication) without
using a strong enough random number generator. This could allow an
attacker to be able to more easily guess the authentication cookie."

https://rhn.redhat.com/errata/RHSA-2003-041.html
SOLUTION
It is recommended that all Gentoo Linux users who are running
net-misc/tightvnc upgrade to tightvnc-1.2.8 as follows:
emerge sync
emerge -u tightvnc
emerge clean
