CVE-2025-7039
Full vulnerability record from the local CVENow database.
Description
A flaw was found in glib. An integer overflow during temporary file creation leads to an out-of-bounds memory access, allowing an attacker to potentially perform path traversal or access private temporary file content by creating symbolic links. This vulnerability allows a local attacker to manipulate file paths and access unauthorized data. The core issue stems from insufficient validation of file path lengths during temporary file operations.

"value": "Se encontró un defecto en glib. Un desbordamiento de entero durante la creación de archivos temporales conduce a un acceso a memoria fuera de límites, permitiendo a un atacante realizar potencialmente un salto de ruta o acceder a contenido de archivos temporales privados mediante la creación de enlaces simbólicos. Esta vulnerabilidad permite a un atacante local manipular rutas de archivos y acceder a datos no autorizados. El problema principal se deriva de una validación insuficiente de las longitudes de las rutas de archivos durante las operaciones de archivos temporales."
