Integer overflow in the dccp_feat_change function in net/dccp/feat.c in the
Datagram Congestion Control Protocol (DCCP) subsystem in the Linux kernel
2.6.18, and 2.6.17 through 2.6.20, allows local users to gain privileges
via an invalid feature length, which leads to a heap-based buffer overflow.
Brandon Edwards discovered that the DCCP system in the kernel did not
correctly check feature lengths. A remote attacker could exploit this
to execute arbitrary code.
