Vulnerability from fkie_nvd - Published: 2009-07-29 17:30 - Updated: 2026-06-16 23:09
Severity
Summary
The Active Template Library (ATL) in Microsoft Visual Studio .NET 2003 SP1, Visual Studio 2005 SP1 and 2008 Gold and SP1, and Visual C++ 2005 SP1 and 2008 Gold and SP1 does not properly enforce string termination, which allows remote attackers to obtain sensitive information via a crafted HTML document with an ATL (1) component or (2) control that triggers a buffer over-read, related to ATL headers and buffer allocation, aka "ATL Null String Vulnerability."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
