Debian DSA-2186-1 : iceweasel - several vulnerabilities

critical Nessus Plugin ID 52618
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


Several vulnerabilities have been discovered in Iceweasel, a web browser based on Firefox. The included XULRunner library provides rendering services for several other applications included in Debian.

- CVE-2010-1585 Roberto Suggi Liverani discovered that the sanitising performed by ParanoidFragmentSink was incomplete.

- CVE-2011-0051 Zach Hoffmann discovered that incorrect parsing of recursive eval() calls could lead to attackers forcing acceptance of a confirmation dialogue.

- CVE-2011-0053 Crashes in the layout engine may lead to the execution of arbitrary code.

- CVE-2011-0054, CVE-2010-0056 Christian Holler discovered buffer overflows in the JavaScript engine, which could allow the execution of arbitrary code.

- CVE-2011-0055 'regenrecht' and Igor Bukanov discovered a use-after-free error in the JSON-Implementation, which could lead to the execution of arbitrary code.

- CVE-2011-0057 Daniel Kozlowski discovered that incorrect memory handling the web workers implementation could lead to the execution of arbitrary code.

- CVE-2011-0059 Peleus Uhley discovered a cross-site request forgery risk in the plugin code.


Upgrade the iceweasel packages.

For the oldstable distribution (lenny), this problem has been fixed in version of the xulrunner source package.

For the stable distribution (squeeze), this problem has been fixed in version 3.5.16-5.
