Name of the Vulnerable Software and Affected Versions: PDF-XChange Editor (affected versions not specified)

Description: This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the parsing of U3D files due to the lack of proper validation of user-supplied data, resulting in a read past the end of an allocated object. An attacker can leverage this to execute code in the context of the current process.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
