Description Anten Skrabec 2022-08-23 00:44:42 UTC

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).
