Detailsinfo

A vulnerability was found in lksctp Stream Control Transmission Protocol up to 2.6.16 and classified as problematic. Affected by this issue is the function sctp_skb_pull. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is availability. CVE summarizes:

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.
