Several remote vulnerabilities have been discovered in the Iceweasel web browser, an unbranded version of the Firefox browser. The Common Vulnerabilities and Exposures project identifies the following problems:

  • CVE-2007-1095

    Michal Zalewski discovered that the unload event handler had access to the address of the next page to be loaded, which could allow information disclosure or spoofing.

  • CVE-2007-2292

    Stefano Di Paola discovered that insufficient validation of user names used in Digest authentication on a web site allows HTTP response splitting attacks.

  • CVE-2007-3511

    It was discovered that insecure focus handling of the file upload control can lead to information disclosure. This is a variant of CVE-2006-2894.

  • CVE-2007-5334

    Eli Friedman discovered that web pages written in Xul markup can hide the titlebar of windows, which can lead to spoofing attacks.

  • CVE-2007-5337

    Georgi Guninski discovered the insecure handling of smb:// and sftp:// URI schemes may lead to information disclosure. This vulnerability is only exploitable if Gnome-VFS support is present on the system.

  • CVE-2007-5338
