--------------------------------------------------------------------- GENTOO LINUX SECURITY ANNOUNCEMENT 200302-16 ---------------------------------------------------------------------
PACKAGE : vnc SUMMARY : insecure cookie generation DATE : 2003-02-24 11:35 UTC EXPLOIT : remote VERSIONS AFFECTED : <3.3.6-r1 FIXED VERSION : 3.3.6-r1
---------------------------------------------------------------------
- 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."
Read the full advisory at: https://rhn.redhat.com/errata/RHSA-2003-041.html
SOLUTION
It is recommended that all Gentoo Linux users who are running net-misc/vnc upgrade to vnc-3.3.6-r1 as follows:
emerge sync emerge -u vnc emerge clean
