Official source
EudorIA operational summary

What it means

Priority 45/100

Ghostscript ha un bug nella gestione di componenti JPEG 2000 con fattori di sottocampionamento non allineati. Un attaccante potrebbe causare un crash o eseguire codice arbitrario se apre un file malizioso. La patch è disponibile per diverse versioni del software. Non è confermato un sfruttamento attivo in rete.

Why it matters

Per le PMI italiane, un attacco a Ghostscript potrebbe compromettere sistemi critici e dati sensibili. La mancanza di patch potrebbe portare a interruzioni di servizio e rischi di esecuzione di codice non autorizzato.
