17 Jun 2025 — A flaw was found in the X server's request handling. Non-zero 'bytes to ignore' in a client's request can cause the server to skip processing another client's request, potentially leading to a denial of service. This update for xorg-x11-server fixes the following issues. Out-of-bounds access in X Rendering extension (Animated cursors). Integer overflow in Big Requests Extension. • https://access.redhat.com/security/cve/CVE-2025-49178 • CWE-667: Improper Locking •

16 Jun 2025 — A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors. These are all security issues fixed in the libxml2-2-2.13.8-2.1 package on the GA media of openSUSE Tumbleweed. • https://access.redhat.com/security/cve/CVE-2025-49794 • CWE-825: Expired Pointer Dereference •

29 May 2025 — A vulnerability was found in systemd-coredump. This flaw allows an attacker to force a SUID process to crash and replace it with a non-SUID binary to access the original's privileged process coredump, allowing the attacker to read sensitive data, such as /etc/shadow content, loaded by the original process. A SUID binary or process has a special type of permission, which allows the process to run with the file owner's permissions, regardless of the user executing the binary.
