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

moz_bug_r_a4 discovered that the protection scheme offered by XPCNativeWrappers
could be bypassed, which might allow privilege escalation.

L. David Baron, Boris Zbarsky, Georgi Guninski, Paul Nickerson, Olli Pettay,
Jesse Ruderman, Vladimir Sukhoy, Daniel Veditz, and Martijn Wargers discovered
crashes in the layout engine, which might allow the execution of arbitrary code.

• CVE-2007-5340

Igor Bukanov, Eli Friedman, and Jesse Ruderman discovered crashes in the
JavaScript engine, which might allow the execution of arbitrary code.

The Mozilla products in the oldstable distribution (sarge) are no longer
