Description Agostino Sarubbo gentoo-dev 2014-03-25 11:55:52 UTC 
CVE-2014-2523 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-2523):

net/netfilter/nf_conntrack_proto_dccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a DCCP packet that triggers a call to the (1) 
dccp_new, (2) dccp_packet, or (3) dccp_error function.
