Microsoft Visual Studio Information Disclosure Vulnerability
An information disclosure vulnerability exists when Visual Studio improperly discloses limited contents of uninitialized memory while compiling program database (PDB) files. An attacker who took advantage of this information disclosure could view uninitialized memory from the Visual Studio instance used to compile the PDB file.
To take advantage of the vulnerability, an attacker would require access to an affected PDB file created using a vulnerable version of Visual Studio. An attacker would have no way to force a developer to produce this information disclosure.
The security update addresses the vulnerability by correcting how PDB files are generated when a project is compiled.
FAQ
In addition to installing this update, are there any further steps I need to carry out to be protected from the vulnerability discussed in this CVE? Visual Studio users who have installed the update for CVE-2018-1037 may also need to rebuild any PDB files that were updated after their initial creation, as they may contain memory leaked from the source computer used to compile Visual Studio projects. This can be done through Visual Studio after installing the applicable update or by running the standalone PDBCopy tool provided by Microsoft (see links in the table below). This tool has been updated to identify and remediate affected PDB files. Note that any projects compiled and then updated through a Visual Studio installation that has not been updated will be susceptible to memory leaks in PDB files.
How will I know which PDB files are affected by this vulnerability? The PDBCopy tool has been updated to assist developers in scanning for and updating affected PDB files. The tool and instructions for use can be found in KB4131751 with direct download links here:
| Architecture | Link |
|---|---|
| X64 | PDBCopy.exe |
| X86 | PDBCopy.exe |
What information is leaked in PDB files compiled with a vulnerable instance of Visual Studio? The memory leaked is limited to typically low-risk variables used in the application build environment, and only information that the Visual Studio executable uses when compiling projects. If your PDB/symbol files are shared publicly, this information could be extracted.
