CVE-2022-23318

Estado: ModificadaAlta (7.1)—

A heap-buffer-overflow in pcf2bdf, versions >= 1.05 allows an attacker to trigger unsafe memory access via a specially crafted PCF font file. This out-of-bound read may lead to an application crash, information disclosure via program memory or other context-dependent impact.

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).
