Title:	CentOS Update for kernel CESA-2012:1064 centos6
Summary:	The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory. Vulnerability Insight: The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * A NULL pointer dereference flaw was found in the nf_ct_frag6_reasm() function in the Linux kernel's netfilter IPv6 connection tracking implementation. A remote attacker could use this flaw to send specially-crafted packets to a target system that is using IPv6 and also has the nf_conntrack_ipv6 kernel module loaded, causing it to crash. (CVE-2012-2744, Important) * A flaw was found in the way the Linux kernel's key management facility handled replacement session keyrings on process forks. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2745, Moderate) Red Hat would like to thank an anonymous contributor working with the Beyond Security SecuriTeam Secure Disclosure program for reporting CVE-2012-2744. This update also fixes the following bugs: * Previously introduced firmware files required for new Realtek chipsets contained an invalid prefix ('rtl_nic_') in the file names, for example '/lib/firmware/rtl_nic/rtl_nic_rtl8168d-1.fw'. This update corrects these file names. For example, the aforementioned file is now correctly named '/lib/firmware/rtl_nic/rtl8168d-1.fw'. (BZ#832359) * This update blacklists the ADMA428M revision of the 2GB ATA Flash Disk device. This is due to data corruption occurring on the said device when the Ultra-DMA 66 transfer mode is used. When the 'libata.force=5:pio0, 6:pio0' kernel parameter is set, the aforementioned device works as expected. (BZ#832363) * On Red Hat Enterprise Linux 6, mounting an NFS export from a server running Windows Server 2012 Release Candidate returned the NFS4ERR_MINOR_VERS_MISMATCH error because Windows Server 2012 Release Candidate supports NFSv4.1 only. Red Hat Enterprise Linux 6 did not properly handle the returned error and did not fall back to using NFSv3, which caused the mount operation to fail. With this update, when the NFS4ERR_MINOR_VERS_MISMATCH error is returned, the mount operation properly falls back to using NFSv3 and no longer fails. (BZ#832365) * On ext4 file systems, when fallocate() failed to allocate blocks due to the ENOSPC condition (no space left on device) for a file larger than 4 GB, the size of the file became corrupted and, consequently, caused file system corruption. This was due to a missing cast operator in the 'ext4_fallocate()' function. With this update, the underlying source code has b ...
