An issue was discovered in GNU gettext 0.19.8. There is a double free in default_add_message in read-catalog.c, related to an invalid free in po_gram_parse in po-gram-gen.y, as demonstrated by lt-msgfmt.
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
