Описание
The SCTP implementation in the Linux kernel before 3.17.4 allows remote attackers to cause a denial of service (memory consumption) by triggering a large number of chunks in an association's output queue, as demonstrated by ASCONF probes, related to net/sctp/inqueue.c and net/sctp/sm_statefuns.c.
A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled the association's output queue. A remote attacker could send specially crafted packets that would cause the system to use an excessive amount of memory, leading to a denial of service.
Отчет
This issue does affect Red Hat Enterprise Linux 6, 7 and Red Hat Enterprise MRG. Future Linux kernel updates for the respective releases will address this issue.
