CVE-2025-0218

When batch jobs are executed by pgAgent, a script is created in a temporary directory and then executed. In versions of pgAgent prior to 4.2.3, an insufficiently seeded random number generator is used when generating the directory name, leading to the possibility for a local attacker to pre-create the directory and thus prevent pgAgent from executing jobs, disrupting scheduled tasks.

Cuando pgAgent ejecuta trabajos por lotes, se crea un script en un directorio temporal y luego se ejecuta. En versiones de pgAgent anteriores a la 4.2.3, se utiliza un generador de números aleatorios con una información insuficiente al generar el nombre del directorio, lo que genera la posibilidad de que un atacante local cree previamente el directorio y, de esta manera, impida que pgAgent ejecute trabajos, lo que interrumpiría las tareas programadas.
