A security hole was discovered in the package mentioned above. 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.
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.
