libxslt

About this tag
libxslt is the GNOME project's widely used XSLT processing library, commonly embedded in Linux distributions, server tools, and software stacks for XML-to-text or XML-to-HTML transformations. Recent discussions on WindowsForum.com focus on multiple disclosed vulnerabilities in libxslt, including heap use-after-free bugs (CVE-2025-7425, CVE-2025-10911) and type confusion issues (CVE-2025-7424, CVE-2025-11731). These flaws can be triggered by specially crafted XSLT stylesheets, leading to memory corruption, application crashes, and denial-of-service conditions. The threads provide guidance on patching and mitigating risks for systems that process untrusted XSLT input, emphasizing the importance of updating libxslt to maintain security and stability.
