Please update the package in your installation as soon as possible or disable the service. ___________________________________________________________________________ 1. Problem Summary Current and previous versions of netscape communicator have a buffer overflow condition in its handling of JPEG files. Specifically, it trusts the purported length of JPEG files provided by the header and can be mislead into reading arbitrary amounts of data, leading to the overwriting of memory. 2. Impact A web site could contain malicious code which would enable remote execution or other malicious behavior as the user of netscape on the client's machine. 3. Solution Please upgrade your packages to match the new revision Update the packages from our ftp server by running the following command: rpm -Fv ftp_path_to_filename Where ftp_path_to_filename is the following: ftp://ftp.turbolinux.com/pub/updates/6.0/security/netscape-communicator-4.74-2.i386.rpm The source RPM can be downloaded here: ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/netscape-communicator-4.74-2.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.
