| Description: | Mozilla Firefox is an open source Web browser.
Several flaws were found in the way Firefox processed certain malformed JavaScript code. A web page containing malicious JavaScript code could cause Firefox to crash or potentially execute arbitrary code as the user running Firefox. (CVE-2007-2867, CVE-2007-2868)
A flaw was found in the way Firefox handled certain FTP PASV commands. A malicious FTP server could use this flaw to perform a rudimentary port-scan of machines behind a user's firewall. (CVE-2007-1562)
Several denial of service flaws were found in the way Firefox handled certain form and cookie data. A malicious web site that is able to set arbitrary form and cookie data could prevent Firefox from functioning properly. (CVE-2007-1362, CVE-2007-2869)
A flaw was found in the way Firefox handled the addEventListener JavaScript method. A malicious web site could use this method to access or modify sensitive data from another web site. (CVE-2007-2870)
