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.
