Descriptions

Poppler prior to and including 22.08.0 contains an integer overflow in the JBIG2 decoder (JBIG2Stream::readTextRegionSeg() in JBIGStream.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-2022-38171 in Xpdf.

Poppler versiones anteriores a 22.08.0 incluyéndola, contiene un desbordamiento de enteros en el descodificador JBIG2 (la función JBIG2Stream::readTextRegionSeg() en el archivo JBIGStream.cc). El procesamiento de un archivo PDF o una imagen JBIG2 especialmente diseñados podría conllevar a un bloqueo o una ejecución de código arbitrario. Esto es similar a la vulnerabilidad descrita por CVE-2022-38171 en Xpdf

An integer overflow issue was discovered in Popplers' JBIG2 decoder in the JBIG2Stream::readTextRegionSeg() function in JBIGStream.cc file. This flaw allows an attacker to trick a user into opening a malformed PDF file or JBIG2 image in the application, triggering an integer overflow, which could result in a crash or may lead to the execution of arbitrary code on the target system.

Two vulnerabilities were discovered in poppler, a PDF rendering library, which could result in denial of service or the execution of arbitrary code if a malformed PDF file or JBIG2 image is processed.
