Description Agostino Sarubbo gentoo-dev 2014-03-25 12:02:37 UTC
CVE-2014-0101 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0101):

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.
