RHSA-2014:1872: Important: kernel security and bug fix update
First published: Tue Nov 18 2014(Updated: )
The kernel packages contain the Linux kernel, the core of any Linux<br>operating system.<br><li> A NULL pointer dereference flaw was found in the way the Linux kernel's</li> Stream Control Transmission Protocol (SCTP) implementation handled<br>simultaneous connections between the same hosts. A remote attacker could<br>use this flaw to crash the system. (CVE-2014-5077, Important)<br>This update also fixes the following bug:<br><li> This update fixes several race conditions between PCI error recovery</li> callbacks and potential calls of the ifup and ifdown commands in the tg3<br>driver. When triggered, these race conditions could cause a kernel crash.<br>(BZ#1142568)<br>All kernel users are advised to upgrade to these updated packages, which<br>contain backported patches to correct these issues. The system must be<br>rebooted for this update to take effect.<br>
