An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked.
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
