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 ...
