Estado: AplazadaBaja (2.1)—

A vulnerability was found in Freedesktop Poppler 26.07.0. The impacted element is the function JBIG2Stream::readCodeTableSeg of the file poppler/JBIG2Stream.cc. Performing a manipulation results in integer overflow. The attack can be initiated remotely. The exploit has been made public and could be used. The patch is named eb87cf711563894649bd0c365baa479401dc6d51. To fix this issue, it is recommended to deploy a patch.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector AV:N UI:P con manipulación de archivo JBIG2 en Poppler requiere interacción del usuario (lectura de PDF). CWE-189/190 (integer overflow) puede causar corrupción de memoria, pero el impacto real no está explicitado en la descripción.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
