This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Windows. 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 JET database engine. Crafted data in an MDB file can trigger an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process.
