CVE-2022-45414

If a Thunderbird user quoted from an HTML email, for example by replying to the email, and the email contained either a VIDEO tag with the POSTER attribute or an OBJECT tag with a DATA attribute, a network request to the referenced remote URL was performed, regardless of a configuration to block remote content. An image loaded from the POSTER attribute was shown in the composer window. These issues could have given an attacker additional capabilities when targetting releases that did not yet have a fix for CVE-2022-3033 which was reported around three months ago. This vulnerability affects Thunderbird < 102.5.1.

Mozilla Thunderbird is a standalone mail and newsgroup client.

This update upgrades Thunderbird to version 102.6.0.

Security Fix(es):

• Mozilla: Arbitrary file read from a compromised content process (CVE-2022-46872)
• Mozilla: Memory safety bugs fixed in Firefox ESR 102.6 and Thunderbird 102.6 (CVE-2022-46878)
• Mozilla: Use-after-free in WebGL (CVE-2022-46880)
• Mozilla: Memory corruption in WebGL (CVE-2022-46881)
• Mozilla: Quoting from an HTML email with certain tags will trigger network requests and load remote content, regardless of a configuration to block remote content (CVE-2022-45414)
• Mozilla: Drag and Dropped Filenames could have been truncated to malicious extensions (CVE-2022-46874)
• Mozilla: Use-after-free in WebGL (CVE-2022-46882)

Quoting from an HTML email with certain tags will trigger network requests and load remote content, regardless of a configuration to block remote content. (CVE-2022-45414)

These are all security issues fixed in the MozillaThunderbird-102.5.1-1.1 package on the GA media of openSUSE Tumbleweed.

This update for MozillaThunderbird fixes the following issues:

Update to version 102.5.1:

• CVE-2022-45414: Quoting from an HTML email with certain tags will trigger network requests and load remote content, regardless of a configuration to block remote content (bsc#1205941).

Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. (CVE-2022-45403, CVE-2022-45404, CVE-2022-45405, CVE-2022-45406, CVE-2022-45408, CVE-2022-45409, CVE-2022-45410, CVE-2022-45411, CVE-2022-45418, CVE-2022-45420, CVE-2022-45421, CVE-2022-46878, CVE-2022-46880, CVE-2022-46881, CVE-2022-46882, CVE-2023-23605)

Armin Ebert discovered that Thunderbird did not properly manage memory while resolving file symlink. If a user were tricked into opening a specially crafted weblink, an attacker could potentially exploit these to cause a denial of service. (CVE-2022-45412)

Sarah Jamie Lewis discovered that Thunderbird did not properly manage network request while handling HTML emails with certain tags. If a user were tricked into opening a specially HTML email, an attacker could potentially exploit these issue and load remote content regardless of a configuration to block remote content. (CVE-2022-45414)

Erik Kraft, Martin Schwarzl, and Andrew McCreight discovered that Thunderbird incorrectly handled keyboard events. An attacker could possibly use this issue to perform a timing side-channel attack and possibly figure out which keys are being pressed. (CVE-2022-45416)

It was discovered that Thunderbird was using an out-of-date libusrsctp library. An attacker could possibly use this library to perform a reentrancy issue on Thunderbird. (CVE-2022-46871)

Nika Layzell discovered that Thunderbird was not performing a check on paste received from cross-processes. An attacker could potentially exploit this to obtain sensitive information. (CVE-2022-46872)

Matthias Zoellner discovered that Thunderbird was not keeping the filename ending intact when using the drag-and-drop event. An attacker could possibly use this issue to add a file with a malicious extension, leading to execute arbitrary code. (CVE-2022-46874)

Hafiizh discovered that Thunderbird was not properly handling fullscreen notifications when the window goes into fullscreen mode. An attacker could possibly use this issue to spoof the user and obtain sensitive information. (CVE-2022-46877)

Tom Schuster discovered that Thunderbird was not performing a validation check on GTK drag data. An attacker could potentially exploits this to obtain sensitive information. (CVE-2023-23598)

Vadim discovered that Thunderbird was not properly sanitizing a curl command output when copying a network request from the developer tools panel. An attacker could potentially exploits this to hide and execute arbitrary commands. (CVE-2023-23599)

Luan Herrera discovered that Thunderbird was not stopping navigation when dragging a URL from a cross-origin iframe into the same tab. An attacker potentially exploits this to spoof the user. (CVE-2023-23601)

Dave Vandyke discovered that Thunderbird did not properly implement CSP policy when creating a WebSocket in a WebWorker. An attacker who was able to inject markup into a page otherwise protected by a Content Security Policy may have been able to inject an executable script. (CVE-2023-23602)

Dan Veditz discovered that Thunderbird did not properly implement CSP policy on regular expression when using console.log. An attacker potentially exploits this to exfiltrate data. (CVE-2023-23603)

It was discovered that Thunderbird did not properly check the Certificate OCSP revocation status when verifying S/Mime signatures. An attacker could possibly use this issue to bypass signature validation check by sending email signed with a revoked certificate. (CVE-2023-0430)
