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 object. This can be leveraged in conjunction with other issues to execute arbitrary code in the context of the current process.
