CVE-2007-2052

Estado: ModificadaMedia (5)—💥 Exploit
Off-by-one error in the PyLocale_strxfrm function in Modules/_localemodule.c for Python 2.4 and 2.5 causes an incorrect buffer size to be used for the strxfrm function, which allows context-dependent attackers to read portions of memory via unknown manipulations that trigger a buffer over-read due to missing null termination.
CVSS

Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
Puntuación base: 5
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 14%
Percentil entre todas las CVEs puntuadas: 96
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.
