Submit #654068: vstakhov libucl 0.9.2 / master commit d8af953 Heap-based Buffer Overflowinfo

Titlevstakhov libucl 0.9.2 / master commit d8af953 Heap-based Buffer Overflow
Descriptionlibucl version 0.9.2 (master commit d8af953) is vulnerable to a heap buffer overflow in the ucl_include_common function of ucl_util.c. The vulnerability arises when parsing crafted input with ucl_parser_add_string, which eventually calls ucl_strnstr. This function performs a strncmp on memory beyond the allocated buffer, leading to out-of-bounds read access.
