Descriptions

Integer overflow in the mod_sftp (aka SFTP) module in ProFTPD 1.3.3d and earlier allows remote attackers to cause a denial of service (memory consumption leading to OOM kill) via a malformed SSH message.

Desbordamiento de enteros en el módulo mod_sftp (también conocido como SFTP) en ProFTPD v1.3.3d y anteriores, permite a atacantes remotos provocar una denegación de servicio (agotamiento de memoria) a través de un mensaje SSH con formato incorrecto.

Integer overflow in the mod_sftp module in ProFTPD 1.3.3d and earlier allows remote attackers to cause a denial of service via a malformed SSH message. Additionally for Mandriva Linux 2010.0 proftpd was upgraded to the same version as in Mandriva Linux 2010.2. The updated packages have been patched to correct this issue.
