Detection & IOCsextracted from sources · hover to see the quote
- →Monitor calls to the GetGlyphOutline() API iterating over all glyphs of a font, particularly when processing TTF files with a malformed 'fpgm' table — this is the trigger mechanism for the vulnerability. ↗
- →Look for kernel crashes (PAGE_FAULT_IN_NONPAGED_AREA / bugcheck 0x50) in win32k.sys at functions bGeneratePath, PATHOBJ_bCloseFigure, vQsplineToPolyBezier, or EngDeleteRgn when processing embedded fonts — these are crash signatures of CVE-2017-8682 exploitation. ↗
- →Inspect TTF font files (especially embedded in documents or web pages) for a modified 'fpgm' table where an instruction has been changed to 'FLIPPT' — this is the specific mutation that triggers the out-of-bounds read/write. ↗
- →Detect web-based delivery: monitor for user navigation to attacker-controlled sites hosting specially crafted embedded fonts, or email/IM lures directing users to such sites, as these are the primary attack vectors for CVE-2017-8682. ↗
- →Detect file-sharing delivery: monitor for document files containing embedded fonts opened by users, as this is a secondary attack vector for CVE-2017-8682. ↗
- →The crash in win32k!vQsplineToPolyBezier+83 (write operation) indicates potential memory corruption leading to arbitrary code execution — treat any such kernel crash during font processing as a high-severity indicator. ↗
- ·Reproduction requires a custom program calling GetGlyphOutline() across all glyphs; passive file-drop alone may not trigger the vulnerability without this API interaction. ↗
- ·The researcher confirmed reproduction only on Windows 7 at time of disclosure; other platforms were not verified. ↗

CVE-2017-8682 [HIGH] Win32k Graphics Remote Code Execution Vulnerability
Win32k Graphics Remote Code Execution Vulnerability
Description: A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
There are multiple ways an attacker could exploit this vulnerability.
In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit this vulnerability and then convince a user to view
