Descriptions

The vsf_filename_passes_filter function in ls.c in vsftpd before 2.3.3 allows remote authenticated users to cause a denial of service (CPU consumption and process slot exhaustion) via crafted glob expressions in STAT commands in multiple FTP sessions, a different vulnerability than CVE-2010-2632.

La función vsf_filename_passes_filter de ls.c de vsftpd en versiones anteriores a la 2.3.3 permite a usuarios autenticados remotos provocar una denegación de servicio (consumo de toda la CPU y agotamiento de los slots de procesos) a través de una expresión glob modificada en comandos STAT en múltiples sesiones FTP. Una vulnerabilidad distinta a la CVE-2010-2632.

Vsftpd versions 2.3.2 on NetBSD and 2.3.0 on Ubuntu suffer from a remote denial of service vulnerability.
