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."

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
