Description
Exploitable
libyang before 5.2.6 contains a heap use-after-free write vulnerability in lyd_parser_set_data_flags that incorrectly updates metadata list pointers when freeing non-head default metadata entries. Attackers can trigger this vulnerability by submitting crafted YANG XML documents with specific metadata attributes to applications parsing untrusted XML data, causing process crashes or potential code execution.
Patched
libyang from v2.0.164 to v2.1.30 was discovered to contain a NULL pointer dereference via the function lysp_stmt_validate_value at lys_parse_mem.c.
