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 
and ID 496024 (Enterprise Manager), ID 496027 and ID 496028 (BIG-IQ), and ID 
495057 (Websafe) to this vulnerability.

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.
