|Summary:||The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.|
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.
The kernel packages contain the Linux kernel, the core of any Linux
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.
* 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.
Red Hat would like to thank an anonymous contributor working with the
Beyond Security SecuriTeam Secure Disclosure program for reporting
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
* 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 mi ...
