Vulnerability Information

WinVerifyTrust Signature Validation Vulnerability - CVE-2012-0151

A remote code execution vulnerability exists in the Windows Authenticode
Signature Verification function used for portable executable (PE) files. An
anonymous attacker could exploit the vulnerability by modifying an existing
signed executable file to leverage unverified portions of the file in such a
way as to add malicious code to the file without invalidating the signature. An
attacker who successfully exploited this vulnerability could take complete
control of an affected system. An attacker could then install programs; view,
change, or delete data; or create new accounts with full user rights.
