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) •

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 •

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.

CVSS: 7.1EPSS: 0%CPEs: 15EXPL: 0CVE-2025-46421 – Libsoup: information disclosure may leads libsoup client sends authorization header to a different host when being redirected by a server
https://notcve.org/view.php?id=CVE-2025-46421
24 Apr 2025 — A flaw was found in libsoup. When libsoup clients encounter an HTTP redirect, they mistakenly send the HTTP Authorization header to the new host that the redirection points to. This allows the new host to impersonate the user to the original host that issued the redirect. 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. • https://access.redhat.com/security/cve/CVE-2025-46421 • CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere •
