CVE-2014-0101

HIGH 7.8EPSS 7.04%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (7.04%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
