========================================================================== Ubuntu Security Notice USN-1925-1 August 07, 2013 thunderbird vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 13.04 - Ubuntu 12.10 - Ubuntu 12.04 LTS Summary: Several security issues were fixed in Thunderbird. Software Description: - thunderbird: Mozilla Open Source mail and newsgroup client Details: Jeff Gilbert and Henrik Skupin discovered multiple memory safety issues in Thunderbird. If the user were tricked in to opening a specially crafted message with scripting enabled, an attacker could possibly exploit these to cause a denial of service via application crash, or potentially execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2013-1701) It was discovered that a document's URI could be set to the URI of a different document. If a user had scripting enabled, an attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2013-1709) A flaw was discovered when generating a CRMF request in certain circumstances. If a user had scripting enabled, an attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2013-1710) Cody Crews discovered that some Javascript components performed security checks against the wrong URI, potentially bypassing same-origin policy restrictions. If a user had scripting enabled, an attacker could exploit this to conduct cross-site scripting (XSS) attacks or install addons from a malicious site. (CVE-2013-1713) Federico Lanusse discovered that web workers could bypass cross-origin checks when using XMLHttpRequest. If a user had scripting enabled, an attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2013-1714) Georgi Guninski and John Schoenick discovered that Java applets could access local files under certain circumstances. If a user had scripting enabled, an attacker could potentially exploit this to steal confidential data. (CVE-2013-1717) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 13.04: thunderbird 17.0.8+build1-0ubuntu0.13.04.1 Ubuntu 12.10: thunderbird 17.0.8+build1-0ubuntu0.12.10.1 Ubuntu 12.04 LTS: thunderbird 17.0.8+build1-0ubuntu0.12.04.1 After a standard system update you need to restart Thunderbird to make all the necessary changes.
