The remote host is missing updates announced in
advisory RHSA-2007:0400.
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)
A flaw was found in the way Firefox displayed certain web content. A
malicious web page could generate content that would overlay user
interface elements such as the hostname and security indicators, tricking
users into thinking they are visiting a different site. (CVE-2007-2871)
Users of Firefox are advised to upgrade to these erratum packages, which
contain Firefox version 1.5.0.12 that corrects these issues.
