CVE-2017-2807

Estado: ModificadaAlta (7.8)—

An exploitable buffer overflow vulnerability exists in the tag parsing functionality of Ledger-CLI 3.1.1. A specially crafted journal file can cause an integer underflow resulting in code execution. An attacker can construct a malicious journal file to trigger this vulnerability.

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).
