CVE-2010-3432 | Ubuntu

The sctp_packet_config function in net/sctp/output.c in the Linux kernel before 2.6.35.6 performs extraneous initializations of packet data structures, which allows remote attackers to cause a denial of service (panic) via a certain sequence of SCTP traffic.

From the Ubuntu Security Team

Thomas Dreibholz discovered that SCTP did not correctly handle appending packet chunks. A remote attacker could send specially crafted traffic to crash the system, leading to a denial of service.
