Overview
During installation, Netscape 6.0.1 creates a temporary file with insecure options and a predictable name in a world-writable location. By using a symbolic link attack, an attacker could cause overwrite of arbitrary files.
Description
The installation script for Netscape 6.0.1 creates a temporary file with a predictable name in /tmp, a world-writable directory. This file is not checked for prior existence or ownership. |
Impact
If the installation is done while the system is in multi-user mode, an attacker may be able to create a symbolic link with appropriate name and cause overwrite of any writable file on the system. |
Solution
The CERT/CC is currently unaware of a practical solution to this problem. |
Perform the install in single-user mode. |
