Linux Kernel Netfilter *_conntrack_proto_sctp.c sctp_new Function Unknown Chunk Type Remote DoS

Medium Nessus Plugin ID 25483


It is possible to crash the remote host by sending it a specially- crafted packet.


There is a flaw in the SCTP code included in Linux kernel versions before that results in a kernel panic when an SCTP packet with an unknown chunk type is received. An attacker can leverage this flaw to crash the remote host with a single, possibly forged, packet.


Upgrade to Linux kernel version or later.
