Who is Vulnerable?
Vulnerability Description The Firefox web browser is an application designed for tasks related to browsing the web, such as displaying HTML pages, downloading files, and so on. On Unix-like systems, Firefox is usually invoked through the start-up script firefox, rather than by directly executing the firefox-bin binary. The firefox script performs some preliminary environment checking and argument parsing, then starts the binary executable. A vulnerability exists in the Firefox browser start-up script. The script does not properly sanitize URLs supplied to it by external programs such as mail applications. This vulnerability can be exploited to run arbitrary shell commands with the privileges of the currently logged in user. A successful exploitation of the vulnerability allows an attacker executes the shell commands with the privileges of the currently logged on user. The behaviour of the system depends on the nature of the injected shell commands.
