CVE-2014-0101

Published: 11 March 2014

The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk.

From the Ubuntu security team

A flaw was discovered in the Linux kernel's handling of the SCTP handshake. A remote attacker could exploit this flaw to cause a denial of service (system crash).

Status

Notes

android kernels (goldfish, grouper, maguro, mako and manta) are not
supported on the Ubuntu Touch 13.10 preview kernels
