CVE-2008-1721

Estado: ModificadaAlta (7.5)—💥 Exploit
Integer signedness error in the zlib extension module in Python 2.5.2 and earlier allows remote attackers to execute arbitrary code via a negative signed integer, which triggers insufficient memory allocation and a buffer overflow.
CVSS

Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
Puntuación base: 7.5
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 23%
Percentil entre todas las CVEs puntuadas: 98
Fecha de la puntuación: 7/10/2026
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).
💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
