CVE-2025-29069
A heap buffer overflow vulnerability has been identified in the lcms2-2.16. The vulnerability exists in the UnrollChunkyBytes function in cmspack.c, which is responsible for handling color space transformations. NOTE: this is disputed by the Supplier because the finding identified a bug in a third-party calling program, not in lcms.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
- Puntuación base: 7.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.41%
- Percentil entre todas las CVEs puntuadas: 34
- Fecha de la puntuación: 6/10/2026
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).

- Explotación
T1190Exploit Public-Facing Applicationinitial access85 % - Impacto principal
T1059Command and Scripting Interpreterexecution75 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation60 %
Vulnerabilidad remota en lcms2 accesible sin autenticación ni interacción (AV:N/AC:L/PR:N/UI:N). Heap buffer overflow (CWE-122) en transformación de espacios de color permite ejecución de código arbitrario remoto (T1190) con potencial escalada de privilegios según contexto.
Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
