CVE-2022-38171
https://notcve.org/view.php?id=CVE-2022-38171
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). Xpdf versiones anteriores a 4.04, contiene un desbordamiento de enteros en el decodificador JBIG2 (la función JBIG2Stream::readSymbolDictSeg() en el archivo JBIG2Stream.cc). El procesamiento de un archivo PDF o una imagen JBIG2 especialmente diseñados podría conllevar a un fallo o una ejecución de código arbitrario. • http://www.openwall.com/lists/oss-security/2022/09/02/11 http://www.xpdfreader.com/security-fixes.html https://dl.xpdfreader.com/xpdf-4.04.tar.gz https://github.com/jeffssh/CVE-2021-30860 https://github.com/zmanion/Vulnerabilities/blob/main/CVE-2022-38171.md https://googleprojectzero.blogspot.com/2021/12/a-deep-dive-into-nso-zero-click.html https://www.cve.org/CVERecord?id=CVE-2021-30860 • CWE-190: Integer Overflow or Wraparound •

CVE-2020-35702
https://notcve.org/view.php?id=CVE-2020-35702
DCTStream::getChars in DCTStream.cc in Poppler 20.12.1 has a heap-based buffer overflow via a crafted PDF document. NOTE: later reports indicate that this only affects builds from Poppler git clones in late December 2020, not the 20.12.1 release. In this situation, it should NOT be considered a Poppler vulnerability. However, several third-party Open Source projects directly rely on Poppler git clones made at arbitrary times, and therefore the CVE remains useful to users of those projects ** EN DISPUTA ** La función DCTStream::getChars en el archivo DCTStream.cc en Poppler versión 20.12.1, presenta un desbordamiento del búfer en la región stack de la memoria por medio de un documento PDF diseñado. NOTA: informes posteriores indican que esto sólo afecta a las construcciones de los clones de git de Poppler a finales de diciembre de 2020, no a la versión 20.12.1. • https://gitlab.freedesktop.org/poppler/poppler/-/issues/1011 • CWE-787: Out-of-bounds Write •
