CVE-2025-1936 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 7.3 High
jar: URLs retrieve local file content packaged in a ZIP archive. The null and everything after it was ignored when retrieving the content from the archive, but the fake extension after the null was used to determine the type of content. This could have been used to hide code in a web extension disguised as something else like an image. This vulnerability was fixed in Firefox 136, Firefox ESR 128.8, Thunderbird 136, and Thunderbird 128.8.

CVE-2025-4083 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 9.1 Critical
A process isolation vulnerability in Thunderbird stemmed from improper handling of javascript: URIs, which could allow content to execute in the top-level document's process instead of the intended frame, potentially enabling a sandbox escape.

CVE-2025-62230 4 Debian, Ibm, Redhat and 1 more 17 Debian Linux, Aix, Vios and 14 more 2026-04-20 7.3 High
A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect.
CVE-2025-62229 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-20 7.3 High
A flaw was found in the X.Org X server and Xwayland when processing X11 Present extension notifications. Improper error handling during notification creation can leave dangling pointers that lead to a use-after-free condition. This can cause memory corruption or a crash, potentially allowing an attacker to execute arbitrary code or cause a denial of service.
CVE-2025-62231 4 Debian, Ibm, Redhat and 1 more 17 Debian Linux, Aix, Vios and 14 more 2026-04-20 7.3 High
A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.
CVE-2026-1761 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift Devspaces and 6 more 2026-04-16 8.6 High
A flaw was found in libsoup. This stack-based buffer overflow vulnerability occurs during the parsing of multipart HTTP responses due to an incorrect length calculation. A remote attacker can exploit this by sending a specially crafted multipart HTTP response, which can lead to memory corruption. This issue may result in application crashes or arbitrary code execution in applications that process untrusted server responses, and it does not require authentication or user interaction.
CVE-2024-47850 2 Cups, Redhat 7 Cups, Enterprise Linux, Rhel Aus and 4 more 2026-04-15 7.5 High
CUPS cups-browsed before 2.5b1 will send an HTTP POST request to an arbitrary destination and port in response to a single IPP UDP packet requesting a printer to be added, a different vulnerability than CVE-2024-47176. (The request is meant to probe the new printer but can be used to create DDoS amplification attacks.)
