sol15910: Linux kernel SCTP vulnerabilities CVE-2014-3673 and CVE-2014-3687
Security Advisory
Original Publication Date: 12/15/2014
Description
CVE-2014-3673
The SCTP implementation in the Linux kernel through 3.17.2 allows remote
attackers to cause a denial of service (system crash) via a malformed ASCONF
chunk, related to net/sctp/sm_make_chunk.c and net/sctp/sm_statefuns.c.
CVE-2014-3687
The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the
SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers
to cause a denial of service (panic) via duplicate ASCONF chunks that trigger
an incorrect uncork within the side-effect interpreter.
Impact
Remote attackers may be able to cause a denial-of-service (DoS) using malformed
or duplicate ASCONF chunk.
Status
F5 Product Development has assigned ID 494662 and ID 494665 (BIG-IP), ID 496023

Recommended action
If the previous table lists a version in the Versions known to be not vulnerable
column, you can eliminate this vulnerability by upgrading to the listed version.
If the table does not list any version in the column, then no upgrade candidate
currently exists. F5 recommends that you limit network access to the management
interface to a secure, management-only network.
For information about the management interface, refer to SOL7312: Overview of the
management port.
