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

Description: This issue allows remote attackers to disclose sensitive information on affected installations. It requires user interaction, such as visiting a malicious page or opening a malicious file. The flaw exists within the parsing of PRC files due to the lack of proper validation of user-supplied data, resulting in a read past the end of an allocated buffer. An attacker can leverage this, potentially in conjunction with other issues, to execute arbitrary 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.
