RHSA-2014:0108-01 -- Redhat kernel

ID: oval:org.secpod.oval:def:501181Date: (C)2014-02-06   (M)2023-12-07
Class: PATCHFamily: unix




The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that the Xen hypervisor did not always lock "page_alloc_lock" and "grant_table.lock" in the same order. This could potentially lead to a deadlock. A malicious guest administrator could use this flaw to cause a denial of service on the host. Red Hat would like to thank the Xen project for reporting this issue. This update also fixes the following bugs: * A recent patch to the CIFS code that introduced the NTLMSSP authentication mechanism caused a regression in CIFS behavior. As a result of the regression, an encryption key that is returned during the SMB negotiation protocol response was only used for the first session that was created on the SMB client. Any subsequent mounts to the same server did not use the encryption key returned by the initial negotiation with the server. As a consequence, it was impossible to mount multiple SMB shares with different credentials to the same server. A patch has been applied to correct this problem so that an encryption key or a server challenge is now provided for every SMB session during the SMB negotiation protocol response. * The igb driver previously used a 16-bit mask when writing values of the flow control high-water mark to hardware registers on a network device. Consequently, the values were truncated on some network devices, disrupting the flow control. A patch has been applied to the igb driver so that it now uses a 32-bit mask as expected. * The IPMI driver did not properly handle kernel panic messages. Consequently, when a kernel panic occurred on a system that was utilizing IPMI without Kdump being set up, a second kernel panic could be triggered. A patch has been applied to the IPMI driver to fix this problem, and a message handler now properly waits for a response to panic event messages. All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
