Descriptions

The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet.

La función sctp_association_free en net/sctp/associola.cen en el kernel de Linux anterior a 3.15.2 no gestiona debidamente cierto valor de backlogs, lo que permite a atacantes remotos causar una denegación de servicio (interrupción del socket) mediante un paquete SCTP manipulado.

An integer underflow flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation processed certain COOKIE_ECHO packets. By sending a specially crafted SCTP packet, a remote attacker could use this flaw to prevent legitimate connections to a particular SCTP server socket to be made.
