https://notcve.org/view.php?id=CVE-2025-4948
19 May 2025 — A flaw was found in the soup_multipart_new_from_message() function of the libsoup HTTP library, which is commonly used by GNOME and other applications to handle web communications. The issue occurs when the library processes specially crafted multipart messages. Due to improper validation, an internal calculation can go wrong, leading to an integer underflow. This can cause the program to access invalid memory and crash. As a result, any application or server using libsoup could be forced to exit unexpected... • https://access.redhat.com/security/cve/CVE-2025-4948 • CWE-191: Integer Underflow (Wrap or Wraparound) •
CVSS: 7.8EPSS: 0%CPEs: 23EXPL: 0CVE-2025-3932 – thunderbird: Tracking Links in Attachments Bypassed Remote Content Blocking
https://notcve.org/view.php?id=CVE-2025-3932
14 May 2025 — It was possible to craft an email that showed a tracking link as an attachment. If the user attempted to open the attachment, Thunderbird automatically accessed the link. The configuration to block remote content did not prevent that. Thunderbird has been fixed to no longer allow access to web pages listed in the X-Mozilla-External-Attachment-URL header of an email. This vulnerability affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1. • https://bugzilla.mozilla.org/show_bug.cgi?id=1960412 • CWE-288: Authentication Bypass Using an Alternate Path or Channel •

14 May 2025 — Thunderbird's handling of the X-Mozilla-External-Attachment-URL header can be exploited to execute JavaScript in the file:/// context. By crafting a nested email attachment (message/rfc822) and setting its content type to application/pdf, Thunderbird may incorrectly render it as HTML when opened, allowing the embedded JavaScript to run without requiring a file download. This behavior relies on Thunderbird auto-saving the attachment to /tmp and linking to it via the file:/// protocol, potentially enabling Ja... • https://bugzilla.mozilla.org/show_bug.cgi?id=1958376 • CWE-290: Authentication Bypass by Spoofing •

https://notcve.org/view.php?id=CVE-2025-3875
14 May 2025 — Thunderbird parses addresses in a way that can allow sender spoofing in case the server allows an invalid From address to be used. For example, if the From header contains an (invalid) value "Spoofed Name ", Thunderbird treats spoofed@example.com as the actual address. This vulnerability affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1.

29 Apr 2025 — A flaw was found in the mod_auth_openidc module for Apache httpd. This flaw allows a remote, unauthenticated attacker to trigger a denial of service by sending an empty POST request when the OIDCPreservePost directive is enabled. The server crashes consistently, affecting availability. A vulnerability has been discovered in mod_auth_openidc, an OpenID Certified authentication and authorization module for the Apache HTTP server that implements the OpenID Connect Relying Party functionality. • https://access.redhat.com/security/cve/CVE-2025-3891 • CWE-248: Uncaught Exception •

15 Apr 2025 — By crafting a malformed file name for an attachment in a multipart message, an attacker can trick Thunderbird into including a directory listing of /tmp when the message is forwarded or edited as a new message. This vulnerability could allow attackers to disclose sensitive information from the victim's system. This vulnerability is not limited to Linux; similar behavior has been observed on Windows as well.

https://notcve.org/view.php?id=CVE-2025-3522
15 Apr 2025 — Thunderbird processes the X-Mozilla-External-Attachment-URL header to handle attachments which can be hosted externally. When an email is opened, Thunderbird accesses the specified URL to determine file size, and navigates to it when the user clicks the attachment. Because the URL is not validated or sanitized, it can reference internal resources like chrome:// or SMB share file:// links, potentially leading to hashed Windows credential leakage and opening the door to more serious security issues.

14 Apr 2025 — A flaw was found in libsoup, where the soup_multipart_new_from_message() function is vulnerable to an out-of-bounds read. This flaw allows a malicious HTTP client to induce the libsoup server to read out of bounds. Tan Wei Chong discovered that libsoup incorrectly handled memory when parsing HTTP request headers. An attacker could possibly use this issue to send a maliciously crafted HTTP request to the server, causing a denial of service.
