Adobe : Security Vulnerabilities, CVEs, Published In 2003 (Code Execution) CVSS score >= 4

Buffer overflow in the WWWLaunchNetscape function of Adobe Acrobat Reader (acroread) 5.0.7 and earlier allows remote attackers to execute arbitrary code via a .pdf file with a long mailto link.

The digital signature mechanism for the Adobe Acrobat PDF viewer only verifies the PE header of executable code for a plug-in, which can allow attackers to execute arbitrary code in certified mode by making the plug-in appear to be signed by Adobe.
