CVE-2026-50257 [HIGH] CWE-416 CVE-2026-50257: A use-after-free flaw was found in the X.Org X server and Xwayland in miSyncDestroyFence(). A client A use-after-free flaw was found in the X.Org X server and Xwayland in miSyncDestroyFence(). A client that sets up multiple fence triggers can trigger a use-after-free function pointer call. An attacker would connect to the X server to set up a fence and await that fence, then a second X connection destroys the fence, causing the use-after-free. This m

CVE-2026-54230 [HIGH] CWE-59 CVE-2026-54230: A symlink following vulnerability was found in the ABRT post-create event handler scripts in librepo A symlink following vulnerability was found in the ABRT post-create event handler scripts in libreport. Event scripts write output files using shell redirections without the O_NOFOLLOW flag. If the target file is replaced with a symlink, the shell process running as root follows the symlink and writes content to the symlink target, allowing arbitrary f

CVE-2026-4271 [HIGH] CWE-416 CVE-2026-4271: A flaw was found in libsoup, a library for handling HTTP requests. This vulnerability, known as a Us A flaw was found in libsoup, a library for handling HTTP requests. This vulnerability, known as a Use-After-Free, occurs in the HTTP/2 server implementation. A remote attacker can exploit this by sending specially crafted HTTP/2 requests that cause authentication failures. This can lead to the application attempting to access memory that has already bee

CVE-2020-1045 [HIGH] CVE-2020-1045: <p>A security feature bypass vulnerability exists in the way Microsoft ASP.NET Core parses encoded c A security feature bypass vulnerability exists in the way Microsoft ASP.NET Core parses encoded cookie names.
