Summary
libxml2 security update
Details

This library allows to manipulate XML files. It includes support to read, modify and write XML and HTML files. There is DTDs support this includes parsing and validation even with complex DtDs, either at parse time or later once the document has been modified. The output can be a simple SAX stream or and in-memory DOM like representations. In this case one can use the built-in XPath and XPointer implementation to select sub nodes or ranges. A flexible Input/Output mechanism is available, with existing HTTP and FTP modules and combined to an URI library.

Security Fix(es):

A flaw was found in libxstl/libxml2. The 'exsltDynMapFunction' function in libexslt/dynamic.c does not contain a recursion depth check, which may cause an infinite loop via a specially crafted XSLT document while handling 'dyn:map()', leading to stack exhaustion and a local denial of service.(CVE-2025-9714)

Severity
