Descriptions

Race condition in the sctp_rcv function in net/sctp/input.c in the Linux kernel before 2.6.29 allows remote attackers to cause a denial of service (system hang) via SCTP packets. NOTE: in some environments, this issue exists because of an incomplete fix for CVE-2011-2482.

Condición de carrera en la función sctp_rcv de net/sctp/input.c en el kernel Linux anteriores a v2.6.29 permite que atacantes remotos provoquen una denegación de servicio (sistema bloqueado) mediante paquetes SCTP. NOTA: en algunos entornos, este problema se produce por una corrección incompleta para CVE-2011-2482.
