Xpdf 4.04 will deadlock on a PDF object stream whose "Length" field is itself in another object stream.

XPDF v4.04 was discovered to contain a stack overflow via the function FileStream::copy() at xpdf/Stream.cc:795.

A stack overflow in the Catalog::readPageLabelTree2(Object) function of XPDF v4.04 allows attackers to cause a Denial of Service (DoS) via a crafted PDF file.

An issue was discovered in Xpdf 4.04. There is a crash in XRef::fetch(int, int, Object, int) in xpdf/XRef.cc, a different vulnerability than CVE-2018-16369 and CVE-2019-16088.

An issue was discovered in Xpdf 4.04. There is a crash in convertToType0 in fofi/FoFiType1C.cc, a different vulnerability than CVE-2022-38928.

An issue was discovered in Xpdf 4.04. There is a crash in gfseek(IOFILE, long, int) in goo/gfile.cc.

Xpdf prior to version 4.04 contains an integer overflow in the JBIG2 decoder (JBIG2Stream::readTextRegionSeg() 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).
