CVE-2013-4350

Publication date 25 September 2013

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The IPv6 SCTP implementation in net/sctp/ipv6.c in the Linux kernel through 3.11.1 uses data structures and function calls that do not trigger an intended configuration of IPsec encryption, which allows remote attackers to obtain sensitive information by sniffing the network.

From the Ubuntu Security Team

Alan Chester reported a flaw in the IPv6 Stream Control Transmission Protocol (SCTP) of the Linux kernel. A remote attacker could exploit this flaw to obtain sensitive information by sniffing network traffic.
