SQLite fts3_tokenizer Untrusted Pointer Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of SQLite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of the fts3_tokenizer function. The issue lies in the optional second argument which is expected to be a pointer into a structure. An attacker can leverage this vulnerability to achieve code execution under the context of the current process.
