Introduction
Windows Graphics Device Interface (GDI) has once again come under scrutiny with the disclosure of CVE-2025-47984, a critical information disclosure vulnerability. This flaw, rooted in a protection mechanism failure, allows attackers to remotely access sensitive data, highlighting persistent security challenges within Microsoft's graphical subsystems.
Technical Information
CVE-2025-47984 is categorized under CWE-693, indicating a protection mechanism failure within Windows GDI. The vulnerability specifically stems from insufficient memory isolation and inadequate boundary checks, allowing attackers to remotely read sensitive memory regions. By crafting malicious network packets targeting the GDI service, attackers can exploit this flaw without authentication, potentially accessing critical information such as session tokens and kernel pointers.
Attack Vectors and Exploitation Methods
Attackers exploit this vulnerability by sending specially crafted network packets to the vulnerable GDI component. Due to the absence of robust memory protection mechanisms, these packets can trigger unauthorized memory disclosures, exposing sensitive system information.
Patch Information
Microsoft has released a security update to address a vulnerability in Microsoft SQL Server, identified as CVE-2025-47984. This vulnerability could allow an attacker to execute arbitrary code on the affected system. The patch modifies the way SQL Server handles certain requests to prevent exploitation. Administrators are advised to apply the update promptly to mitigate potential risks.
