Alexander Reichle-Schmehl uploaded new packages for iceweasel which
fixed the following security problems:
CVE-2010-3174
CVE-2010-3176
Multiple unspecified vulnerabilities in the browser engine in
Iceweasel allow remote attackers to cause a denial of service
(memory corruption and application crash) or possibly execute
arbitrary code via unknown vectors.
CVE-2010-3177
Multiple cross-site scripting (XSS) vulnerabilities in the
Gopher parser in Iceweasel allow remote attackers to inject
arbitrary web script or HTML via a crafted name of a (1) file
or (2) directory on a Gopher server.
CVE-2010-3178
Iceweasel does not properly handle certain modal calls made by
javascript: URLs in circumstances related to opening a new
window and performing cross-domain navigation, which allows
remote attackers to bypass the Same Origin Policy via a
crafted HTML document.
CVE-2010-3179
Stack-based buffer overflow in the text-rendering
functionality in Iceweasel allows remote attackers to execute
arbitrary code or cause a denial of service (memory corruption
and application crash) via a long argument to the
document.write method.
CVE-2010-3180
Use-after-free vulnerability in the nsBarProp function in
Iceweasel allows remote attackers to execute arbitrary code by
accessing the locationbar property of a closed window.
CVE-2010-3183
The LookupGetterOrSetter function in Iceweasel does not
properly support window.__lookupGetter__ function calls that
lack arguments, which allows remote attackers to execute
arbitrary code or cause a denial of service (incorrect pointer
dereference and application crash) via a crafted HTML
document.
For the lenny-backports distribution the problems have been fixed in
version 3.5.15-1~bpo50+1.
Upgrade instructions
--------------------
If you don't use pinning (see [1]) you have to update the package
manually via "apt-get -t lenny-backports install <packagelist>" with
the packagelist of your installed packages affected by this update.
[1] <https://backports.debian.org/Instructions>
We recommend to pin (in /etc/apt/preferences) the backports repository
to 200 so that new versions of installed backports will be installed
automatically.
