CVE-2018-12405

Mozilla developers and community members reported memory safety bugs present in Firefox 63 and Firefox ESR 60.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.

A buffer overflow and out-of-bounds read can occur in TextureStorage11 within the ANGLE graphics library, used for WebGL content. This results in a potentially exploitable crash (CVE-2018-17466).

A use-after-free vulnerability can occur after deleting a selection element due to a weak reference to the select element in the options collection. This results in a potentially exploitable crash (CVE-2018-18492).

A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash (CVE-2018-18493).

A same-origin policy violation allowing the theft of cross-origin URL entries when using the Javascript location property to cause a redirection to another site using performance.getEntries(). This is a same-origin policy violation and could allow for data theft (CVE-2018-19494).

A potential vulnerability leading to an integer overflow can occur during buffer size calculations for images when a raw value is used instead of the checked value. This leads to a possible out-of-bounds write (CVE-2018-18498).

Memory safety bugs present in Firefox ESR 60.3, some of which showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code (CVE-2018-12405).

This update for MozillaThunderbird to version 60.5.1 fixes the following issues:

Other bug fixes and changes:

• FileLink provider WeTransfer to upload large attachments
• Thunderbird now allows the addition of OpenSearch search engines from a local XML file using a minimal user inferface: [+] button to select a file an add, [-] to remove.
• More search engines: Google and DuckDuckGo available by default in some locales
• During account creation, Thunderbird will now detect servers using the Microsoft Exchange protocol. It will offer the installation of a 3rd party add-on (Owl) which supports that protocol.
• Thunderbird now compatible with other WebExtension-based FileLink add-ons like the Dropbox add-on
• New WebExtensions FileLink API to facilitate add-ons
• Fix decoding problems for messages with less common charsets (cp932, cp936)
• New messages in the drafts folder (and other special or virtual folders) will no longer be included in the new messages notification
• Thunderbird 60 will migrate security databases (key3.db, cert8.db to key4.db, cert9.db). Thunderbird 60.3.2 and earlier contained a fault that potentially deleted saved passwords and private certificate keys for users using a master password. Version 60.3.3 will prevent the loss of data; affected users who have already upgraded to version 60.3.2 or earlier can restore the deleted key3.db file from backup to complete the migration.
• Address book search and auto-complete slowness introduced in Thunderbird 60.3.2
• Plain text markup with * for bold, / for italics, _ for underline and | for code did not work when the enclosed text contained non-ASCII characters
• While composing a message, a link not removed when link location was removed in the link properties panel
• Encoding problems when exporting address books or messages using the system charset. Messages are now always exported using the UTF-8 encoding
• If the 'Date' header of a message was invalid, Jan 1970 or Dec 1969 was displayed. Now using date from 'Received' header instead.
• Body search/filtering didn't reliably ignore content of tags
• Inappropriate warning 'Thunderbird prevented the site (addons.thunderbird.net) from asking you to install software on your computer' when installing add-ons
• Incorrect display of correspondents column since own email address was not always detected
• Spurious (encoded newline) inserted into drafts and sent email
• Double-clicking on a word in the Write window sometimes launched the Advanced Property Editor or Link Properties dialog
• Fixe Cookie removal
• 'Download rest of message' was not working if global inbox was used
• Fix Encoding problems for users (especially in Poland) when a file was sent via a folder…
