Xpdf prior to version 4.04 contains an integer overflow in the JBIG2 decoder (JBIG2Stream::readSymbolDictSeg() in JBIG2Stream.cc). Processing a specially crafted PDF file or JBIG2 image could lead to a crash or the execution of arbitrary code. This is similar to the vulnerability described by CVE-2021-30860 (Apple CoreGraphics). https://dl.xpdfreader.com/old/xpdf-4.04.tar.gz http://www.xpdfreader.com/security-fixes.html https://dl.xpdfreader.com/xpdf-4.04.tar.gz
