Use of Uninitialized Heap Memory – Arbitrary Write Vulnerability
This vulnerability allows remote attackers to execute code on vulnerable installations of Foxit Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of PDF files. The issue results from the lack of proper validation of user-supplied data which can result in a read uninitialized memory past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process.
