_____________________________________________________________________________________________
A security hole has been discovered in the netscape-communicator
package. Please update the packages in your installation as soon as
possible.
_____________________________________________________________________________________________
1. Problem Summary
The Netscape browser does not escape the gif file comment in the
image information page. This allows javascript execution in the
"about:" protocol and can for example be used to upload the
History (about:global) to a webserver.
2. Impact
It is possible for a user to view a history of URLs visited on a
remote system.
3. Solution
Update the packages from our ftp server by running the following
command:
rpm -Uvh ftp_path_to_filename
Where ftp_path_to_filename is the following:
ftp://ftp.turbolinux.com/pub/updates/6.0/security/netscape-communicator-4.77-3.i386.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/netscape-communicator-4.77-3.src.rpm
**Note: You must rebuild and install the RPM if you choose to
download and install the SRPM. Simply installing the SRPM alone
WILL NOT CLOSE THE SECURITY HOLE.
Please verify the MD5 checksums of the updates before you install:
MD5 sum Package Name
