--------------------------------------------------------------------- Fedora Update Notification FEDORA-2005-606 2005-07-20 --------------------------------------------------------------------- Product : Fedora Core 4 Name : thunderbird Version : 1.0.6 Release : 1.1.fc4 Summary : Mozilla Thunderbird mail/newsgroup client Description : Mozilla Thunderbird is a standalone mail and newsgroup client. --------------------------------------------------------------------- Update Information: Mozilla Thunderbird is a standalone mail and newsgroup client. A bug was found in the way Thunderbird handled anonymous functions during regular expression string replacement. It is possible for a malicious HTML mail to capture a random block of client memory. The Common Vulnerabilities and Exposures project has assigned this bug the name CAN-2005-0989. A bug was found in the way Thunderbird validated several XPInstall related JavaScript objects. A malicious HTML mail could pass other objects to the XPInstall objects, resulting in the JavaScript interpreter jumping to arbitrary locations in memory. (CAN-2005-1159) A bug was found in the way the Thunderbird privileged UI code handled DOM nodes from the content window. An HTML message could install malicious JavaScript code or steal data when a user performs commonplace actions such as clicking a link or opening the context menu. (CAN-2005-1160) A bug was found in the way Thunderbird executed JavaScript code. JavaScript executed from HTML mail should run with a restricted access level, preventing dangerous actions. It is possible that a malicious HTML mail could execute JavaScript code with elevated privileges, allowing access to protected data and functions. (CAN-2005-1532) A bug was found in the way Thunderbird executed Javascript in XBL controls. It is possible for a malicious HTML mail to leverage this vulnerability to execute other JavaScript based attacks even when JavaScript is disabled. (CAN-2005-2261) A bug was found in the way Thunderbird handled certain Javascript functions. It is possible for a malicious HTML mail to crash the client by executing malformed Javascript code. (CAN-2005-2265) A bug was found in the way Thunderbird handled child frames. It is possible for a malicious framed HTML mail to steal sensitive information from its parent frame. (CAN-2005-2266) A bug was found in the way Thunderbird handled DOM node names. It is possible for a malicious HTML mail to overwrite a DOM node name, allowing certain privileged chrome actions to execute the malicious JavaScript. (CAN-2005-2269) A bug was found in the way Thunderbird cloned base objects. It is possible for HTML content to navigate up the prototype chain to gain access to privileged chrome objects. (CAN-2005-2270) Users of Thunderbird are advised to upgrade to this updated package that contains Thunderbird version 1.0.6 and is not vulnerable to these issues. --------------------------------------------------------------------- * Wed Jul 20 2005 Christopher Aillon <caillon@xxxxxxxxxx> 1.0.6-1.1.fc4 - Update to 1.0.6 * Mon Jul 18 2005 Christopher Aillon <caillon@xxxxxxxxxx> 1.0.6-0.1.fc4 - 1.0.6 Release Candidate --------------------------------------------------------------------- This update can be downloaded from: http://download.fedora.redhat.com/pub/fedora/linux/core/updates/4/ 51f614a0a887ffb58ce6bbf4f4eb7431 SRPMS/thunderbird-1.0.6-1.1.fc4.src.rpm fc206b1fd0dccb15da66b2fe3b272175 ppc/thunderbird-1.0.6-1.1.fc4.ppc.rpm 0b94083b2f2415f84069e30c20742ec1 ppc/debug/thunderbird-debuginfo-1.0.6-1.1.fc4.ppc.rpm 38da7902f6e1bcfc45ef688e04a770e8 x86_64/thunderbird-1.0.6-1.1.fc4.x86_64.rpm 1a6bbee24e0559176e19ba1218d91e02 x86_64/debug/thunderbird-debuginfo-1.0.6-1.1.fc4.x86_64.rpm f858562b2d77180acb6d40022fe1c3cd i386/thunderbird-1.0.6-1.1.fc4.i386.rpm 90cba454ded9c8d4e049262abdea64d2 i386/debug/thunderbird-debuginfo-1.0.6-1.1.fc4.i386.rpm This update can also be installed with the Update Agent; you can launch the Update Agent with the 'up2date' command. ---------------------------------------------------------------------
