Description

Linux SCTP (lksctp) before 2.6.17 allows remote attackers to cause a denial of service (infinite recursion and crash) via a packet that contains two or more DATA fragments, which causes an skb pointer to refer back to itself when the full message is reassembled, leading to infinite recursion in the sctp_skb_pull function.

Affected products

Lksctp Stream Control Transmission Protocol: 2.6.17
