| Description |
A vulnerability causing undefined behavior was discovered in the Schematron in the libxml2. The issue arises in the xmlSchematronFormatReport function when processing sch:name elements, leading to memory corruption and undefined behavior when accessing namespace information.
Memory corruption occurs during namespace processing, resulting in the assignment of a corrupted pointer (0xffffffffffffffff) to node->ns. When the code attempts to access node->ns->prefix, it dereferences this invalid pointer, causing undefined behavior. |
