VID 12088
Severity 30
Port
Protocol SCTP
Class Protocol
Detailed Description The Linux host is vulnerable to a denial of service attack via the SCTP packet with unexpected ECNE chunk. The Linux Kernel Stream Control Transmission Protocol (lksctp) project is an implementation of the Stream Control Transmission Protocol (SCTP) in the Linux kernel. The SCTP implementation in Linux kernel versions 2.6.16.x prior to 2.6.17 could allow a remote attacker to cause a denial of service, caused by improper handling of ECNE chunks that are received in the CLOSED state. A remote attacker could exploit this vulnerability to cause a kernel panic.
