| CVE-2025-32989 | 2 Gnu, Redhat | 10 Gnutls, Ceph Storage, Discovery and 7 more | 2026-04-20 | 5.3 Medium |
| A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly. | ||||
| CVE-2025-32988 | 2 Gnu, Redhat | 10 Gnutls, Ceph Storage, Discovery and 7 more | 2026-04-20 | 6.5 Medium |
| A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior. | ||||

This vulnerability was fixed in Firefox 141, Firefox ESR 115.26, Firefox ESR 128.13, Firefox ESR 140.1, Thunderbird 141, Thunderbird 128.13, and Thunderbird 140.1. | ||||
| CVE-2025-3522 | 2 Mozilla, Redhat | 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more | 2026-04-20 | 6.3 Medium |
| 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. This vulnerability was fixed in Thunderbird 137.0.2 and Thunderbird 128.9.2. | ||||
| CVE-2025-2817 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2026-04-20 | 8.8 High |
| Thunderbird's update mechanism allowed a medium-integrity user process to interfere with the SYSTEM-level updater by manipulating the file-locking behavior. By injecting code into the user-privileged process, an attacker could bypass intended access controls, allowing SYSTEM-level file operations on paths controlled by a non-privileged user and enabling privilege escalation. This vulnerability was fixed in Firefox 138, Firefox ESR 128.10, Firefox ESR 115.23, Thunderbird 138, and Thunderbird 128.10. | ||||
| CVE-2025-4091 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2026-04-20 | 8.1 High |
| Memory safety bugs present in Firefox 137, Thunderbird 137, Firefox ESR 128.9, and Thunderbird 128.9. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability was fixed in Firefox 138, Firefox ESR 128.10, Thunderbird 138, and Thunderbird 128.10. | ||||
| CVE-2025-5263 | 2 Mozilla, Redhat | 7 Firefox, Enterprise Linux, Rhel Aus and 4 more | 2026-04-20 | 4.3 Medium |
| Error handling for script execution was incorrectly isolated from web content, which could have allowed cross-origin leak attacks. This vulnerability was fixed in Firefox 139, Firefox ESR 115.24, Firefox ESR 128.11, Thunderbird 139, and Thunderbird 128.11. | ||||
| CVE-2025-5264 | 2 Mozilla, Redhat | 7 Firefox, Enterprise Linux, Rhel Aus and 4 more | 2026-04-20 | 4.8 Medium |
| Due to insufficient escaping of the newline character in the “Copy as cURL” feature, an attacker could trick a user into using this command, potentially leading to local code execution on the user's system. This vulnerability was fixed in Firefox 139, Firefox ESR 115.24, Firefox ESR 128.11, Thunderbird 139, and Thunderbird 128.11. | ||||
| CVE-2025-6424 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Enterprise Linux and 5 more | 2026-04-20 | 9.8 Critical |
| A use-after-free in FontFaceSet resulted in a potentially exploitable crash. This vulnerability was fixed in Firefox 140, Firefox ESR 115.25, Firefox ESR 128.12, Thunderbird 140, and Thunderbird 128.12. | ||||
| CVE-2025-6429 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Enterprise Linux and 5 more | 2026-04-20 | 6.5 Medium |
| Firefox could have incorrectly parsed a URL and rewritten it to the youtube.com domain when parsing the URL specified in an `embed` tag. This could have bypassed website security checks that restricted which domains users were allowed to embed. This vulnerability was fixed in Firefox 140, Firefox ESR 128.12, Thunderbird 140, and Thunderbird 128.12. | ||||
| CVE-2025-10536 | 2 Mozilla, Redhat | 4 Firefox, Firefox Esr, Thunderbird and 1 more | 2026-04-20 | 6.2 Medium |

| CVE-2025-13601 | 2 Gnome, Redhat | 41 Glib, Ceph Storage, Codeready Linux Builder and 38 more | 2026-04-20 | 7.7 High |
| A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string. | ||||
| CVE-2025-0237 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2026-04-20 | 5.4 Medium |
| The WebChannel API, which is used to transport various information across processes, did not check the sending principal but rather accepted the principal being sent. This could have led to privilege escalation attacks. This vulnerability was fixed in Firefox 134, Firefox ESR 128.6, Thunderbird 134, and Thunderbird 128.6. | ||||
| CVE-2025-0238 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2026-04-20 | 5.3 Medium |
