Microsoft Windows Raw Image Extension: Heap-based buffer overflow leading to code execution
Summary
A heap-based buffer overflow in the Windows Raw Image Extension allows an attacker to execute code over a network. According to the CVSS vector, exploitation requires user interaction, for example opening, previewing or downloading a malicious image file. The CVSS base score is 8.8 (High) with high impact on confidentiality, integrity and availability.
Affected
- Microsoft Raw Image Extension 2.1.0.0 to before the fixed build (affected range from the CVE record and third-party trackers; not yet confirmed by the vendor)
Fixed in
- Unknown. The fixed build has not been confirmed by MSRC at the time of writing.
Workaround
- No vendor workaround known.
Exploitation
- Not known to be exploited at the time of writing (CISA SSVC: exploitation none; not listed in CISA KEV according to third-party trackers).
- No public proof of concept found so far.
Our recommendation
- Check the MSRC advisory for the fixed build and update the Raw Image Extension package via Microsoft Store or Windows Update as soon as it is available.
- Until then, limit opening, previewing and downloading untrusted image files on Windows endpoints.
- Prioritise Windows workstations that handle external files.
- Monitor the MSRC entry and CISA KEV for changes.
