GHSA-2jx3-ff3v-j7jj: yara-x: Unvalidated deserialization in safe `Rules::deserialize` allows memory corruption and UB

The yara-x library has a vulnerability in its `Rules::deserialize` function, which accepts untrusted data and reconstructs internal lookup tables without validating them. When malformed serialized bytes are passed in, subsequent safe operations like scanning can trigger out-of-bounds memory reads (undefined behavior, unpredictable crashes or memory corruption) because the code uses unsafe operations that assume the internal structures are valid. This means an attacker could craft a malicious serialized rules file to crash or corrupt a program using this library.
