CVE-2021-30470

Name of the Vulnerable Software and Affected Versions PoDoFo version 0.9.7

Description A flaw was found in the software, where an uncontrolled recursive call among PdfTokenizer::ReadArray(), PdfTokenizer::GetNextVariant(), and PdfTokenizer::ReadDataType() functions can lead to a stack overflow.

Recommendations For PoDoFo version 0.9.7, consider restricting the use of the PdfTokenizer functions to minimize the risk of exploitation until a patch is available. As a temporary workaround, avoid using the ReadArray(), GetNextVariant(), and ReadDataType() functions in the PdfTokenizer class. At the moment, there is no information about a newer version that contains a fix for this issue.
