A flaw has been found in PoDoFo 1.1.0-dev. This issue affects the function PdfTokenizer::DetermineDataType of the file src/podofo/main/PdfTokenizer.cpp of the component PDF Dictionary Parser. Executing manipulation can lead to use after free. It is possible to launch the attack on the local host. The exploit has been published and may be used. This patch is called 22d16cb142f293bf956f66a4d399cdd65576d36c. A patch should be applied to remediate this issue.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
