"value": "Net::IP::LPM versions before 1.11 for Perl allow a heap out-of-bounds read via an unbounded prefix length.\n\nadd() passes the prefix string to the trie builder addPrefixToTrie() without checking it against the address width.\n\naddPrefixToTrie() then walks the prefix buffer by prefix_length bits, reading prefix[byte] for byte up to prefix_len/8, where prefix is the 4-byte (IPv4) or 16-byte (IPv6) packed address. A prefix length greater than 32 for IPv4 or 128 for IPv6, for example add(\"1.2.3.4/255\", $v) or add(\"2001:db8::/255\", $v), reads past the end of the packed address.\n\nThe out-of-bounds read happens during trie construction and is bounded: the prefix length is stored as an unsigned char, so the bit walk reads at most 32 bytes from the start of the packed address, a short distance past the end of the 4-byte or 16-byte buffer. It is detectable under AddressSanitizer, valgrind, or a hardened allocator, where it can abort the process. Lookups and dump() format only the valid address width, so the out-of-bounds bytes are not exposed through the module's API."
