Description This issue allows remote attackers to execute arbitrary code on vulnerable 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 PDF documents, specifically by manipulating a document's elements to cause a pointer to be reused after it has been freed, allowing an attacker to execute code in the context of the current process.
