CVE-2018-14320

This vulnerability allows remote attackers to disclose sensitive
information on vulnerable installations of PoDoFo. 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
PdfEncoding::ParseToUnicode. The issue results from the lack of proper
validation of user-supplied data, which can result in a memory corruption
condition. An attacker can leverage this in conjunction with other
vulnerabilities to execute arbitrary code in the context of the current
process. Was ZDI-CAN-5673.
