Technical details
An out-of-bounds read vulnerability exists in Microsoft Office, allowing an attacker to read memory beyond intended boundaries. The vulnerability can be exploited remotely over a network, requiring no user authentication but likely requiring the victim to open a specially crafted file or interact with malicious content. A successful exploit permits information disclosure, enabling the attacker to extract sensitive data from Office processes. While not yet actively exploited in the wild, the public disclosure indicates patches are or will be available from Microsoft.
