PoDoFo Project PoDoFo any version

Heap-based buffer overflow in the PdfParser::ReadXRefSubsection function in base/PdfParser.cpp in PoDoFo allows attackers to have unspecified impact via vectors related to m_offsets.size.

A heap-use-after free in the PdfTokenizer::ReadDictionary function of podofo v0.10.0 to v0.10.5 allows attackers to cause a Denial of Service (DoS) by supplying a crafted PDF file. NOTE: this is disputed by the Supplier because there is no available file to reproduce the issue.

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.
