____________________________________________________________________________________________ _
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:
netscape-communicator-4.77-3.i386.rpm
The source RPM can be downloaded here:
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 ------------------------------------------------------------------------------------------- - 1c22d82709154a5541cf01e8561651c4 netscape-communicator-4.77-3.i386.rpm a0973f4123b0a6bba0279e403cae4772 netscape-communicator-4.77-3.src.rpm ____________________________________________________________________________________________ _
These packages are GPG signed by Turbolinux for security. Our key is available here:
http://www.turbolinux.com/security/tlgpgkey.asc
To verify a package, use the following command:
rpm --checksig name_of_rpm
To examine only the md5sum, use the following command:
md5sum name_of_rpm
**Note: Checking GPG keys requires RPM 3.0 or higher.
