CVE-2013-3900 · Severity: critical · CVSS 8.8 · Exploited in the wild · Published 2022-01-10

A remote code execution vulnerability exists in the WinVerifyTrust function's handling of Windows Authenticode signature verification for Portable Executable (PE) files. An attacker can modify a signed executable to include malicious code in unverified portions of the file without invalidating the digital signature. Successful exploitation requires a user to run or install a specially crafted, signed PE file, potentially granting the attacker complete control over the affected system.
