In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn’t
reset under certain circumstances. If the relevant memory area happened to
be freed and reused in a certain way, a bounds check could fail and memory
outside a buffer could be written to, or uninitialized data could be
disclosed.
