CWE-476  (opens in a new tab)

How to fix?

Upgrade RHEL:6 perf to version 0:2.6.32-504.8.1.el6 or higher.
This issue was patched in RHSA-2015:0087.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The sctp_process_param function in net/sctp/sm_make_chunk.c in the SCTP implementation in the Linux kernel before 3.17.4, when ASCONF is used, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via a malformed INIT chunk.
