Vulnerabilidad alta de subdesbordamiento entero en NASA cFS hasta versión 7.0.1

Se ha identificado una falla de seguridad en NASA cFS (Core Flight System) versiones hasta 7.0.1 en la función CFE_SB_GetUserDataLength del módulo cFE Software Bus. Un atacante remoto puede manipular los parámetros TotalMsgSize/HdrSize para provocar un subdesbordamiento entero, potencialmente comprometiendo sistemas aeroespaciales, satélites y aplicaciones embebidas altas en instituciones y empresas de LATAM. Con CVSS 7.4, este vector afecta directamente a organizaciones que utilizan sistemas de vuelo autónomo o infraestructura satelital.

A flaw was found in GIMP's PSD file format plugin. This vulnerability, an unsigned integer underflow in the `block_rem` variable, occurs when a user opens a specially crafted `.psd` image file. The underflow leads to parser confusion, enabling an attacker to inject arbitrary data as layer resource blocks. This can ultimately result in arbitrary code execution, allowing the attacker to run maliciou…
