iTextPDF in iText 7 and up to (excluding 4.4.13.3) 7.1.17 allows command injection via a CompareTool filename that is mishandled on the gs (aka Ghostscript) command line in GhostscriptHelper.java.
The XML parsers in iText before 5.5.12 and 7.x before 7.0.3 do not disable external entities, which might allow remote attackers to conduct XML external entity (XXE) attacks via a crafted PDF.
iText v7.1.17, up to (exluding)": 7.1.18 and 7.2.2 was discovered to contain an out-of-memory error via the component readStreamBytesRaw, which allows attackers to cause a Denial of Service (DoS) via a crafted PDF file.
iText v7.1.17 was discovered to contain a stack-based buffer overflow via the component ByteBuffer.append, which allows attackers to cause a Denial of Service (DoS) via a crafted PDF file.
iText v7.1.17 was discovered to contain an out-of-bounds exception via the component ARCFOUREncryption.encryptARCFOUR, which allows attackers to cause a Denial of Service (DoS) via a crafted PDF file. NOTE: Vendor does not view this as a vulnerability and has not found it to be exploitable.
