Description Stefan Behte (RETIRED) gentoo-dev Security 2008-10-21 22:34:12 UTC 
CVE-2008-4445 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-4445):
  The sctp_auth_ep_set_hmacs function in net/sctp/auth.c in the Stream
  Control Transmission Protocol (sctp) implementation in the Linux
  kernel before 2.6.26.4, when the SCTP-AUTH extension is enabled, does
  not verify that the identifier index is within the bounds established
  by SCTP_AUTH_HMAC_ID_MAX, which allows local users to obtain
  sensitive information via a crafted SCTP_HMAC_IDENT IOCTL request
  involving the sctp_getsockopt function, a different vulnerability
  than CVE-2008-4113.
