    Security issues fixed with this release:
    CVE-2010-1188     Use-after-free vulnerability in net/ipv4/tcp_input.c in the Linux kernel 2.6 before 2.6.20, when     IPV6_RECVPKTINFO is set on a listening socket, allows remote attackers to cause a denial of service     (kernel panic) via a SYN packet while the socket is in a listening (TCP_LISTEN) state, which is not     properly handled causes the skb structure to be freed.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5.4 Extended Update Support.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security fixes :

* a race condition was found in the mac80211 implementation, a framework used for writing drivers for wireless devices. An attacker could trigger this flaw by sending a Delete Block ACK (DELBA) packet to a target system, resulting in a remote denial of service. Note:
This issue only affected users on 802.11n networks, and that also use the iwlagn driver with Intel wireless hardware. (CVE-2009-4027, Important)

* a use-after-free flaw was found in the tcp_rcv_state_process() function in the Linux kernel TCP/IP protocol suite implementation. If a system using IPv6 had the IPV6_RECVPKTINFO option set on a listening socket, a remote attacker could send an IPv6 packet to that system, causing a kernel panic (denial of service). (CVE-2010-1188, Important)

* a flaw was found in the gfs2_lock() implementation. The GFS2 locking code could skip the lock operation for files that have the S_ISGID bit (set-group-ID on execution) in their mode set. A local, unprivileged user on a system that has a GFS2 file system mounted could use this flaw to cause a kernel panic (denial of service). (CVE-2010-0727, Moderate)

* a divide-by-zero flaw was found in the ext4 file system code. A local attacker could use this flaw to cause a denial of service by mounting a specially crafted ext4 file system. (CVE-2009-4307, Low)

Bug fixes :

* if a program that calls posix_fadvise() were compiled on x86, and then run on a 64-bit system, that program could experience various problems, including performance issues and the call to posix_fadvise() failing, causing the program to not run as expected or even abort.
With this update, when such programs attempt to call posix_fadvise() on 64-bit systems, sys32_fadvise64() is called instead, which resolves this issue. This update also fixes other 32-bit system calls that were mistakenly called on 64-bit systems (including systems running the kernel-xen kernel). (BZ#569597)

* on some systems able to set a P-State limit via the BIOS, it was not possible to set the limit to a higher frequency if the system was rebooted while a low limit was set:
'/sys/devices/system/cpu/cpu[x]/cpufreq/scaling_max_freq' would retain the low limit in these situations. With this update, limits are correctly set, even after being changed after a system reboot.
(BZ#569727)

* certain Intel ICH hardware (using the e1000e driver) has an NFS filtering capability that did not work as expected, causing memory corruption, which could lead to kernel panics, or other unexpected behavior. In a reported case, a panic occurred when running NFS connection tests. This update resolves this issue by disabling the filtering capability. (BZ#569797)

* if 'open(/proc/[PID]/[xxxx])' was called at the same time the process was exiting, the call would fail with an EINVAL error (an incorrect error for this situation). With this update, the correct error, ENOENT, is returned in this situation. (BZ#571362)

* multiqueue is used for transmitting data, but a single queue transmit ON/OFF scheme was used. This led to a race condition on systems with the bnx2x driver in situations where one queue became full, but not stopped, and the other queue enabled transmission. With this update, only a single queue is used. (BZ#576951)

* the '/proc/sys/vm/mmap_min_addr' tunable helps prevent unprivileged users from creating new memory mappings below the minimum address. The sysctl value for mmap_min_addr could be changed by a process or user that has an effective user ID (euid) of 0, even if the process or user does not have the CAP_SYS_RAWIO capability. This update adds a capability check for the CAP_SYS_RAWIO capability before allowing the mmap_min_addr value to be changed. (BZ#577206)

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

Updated kernel packages that fix one security issue and add one enhancement are now available for Red Hat Enterprise Linux 4.7 Extended Update Support.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issue :

* a use-after-free flaw was found in the tcp_rcv_state_process() function in the Linux kernel TCP/IP protocol suite implementation. If a system using IPv6 had the IPV6_RECVPKTINFO option set on a listening socket, a remote attacker could send an IPv6 packet to that system, causing a kernel panic (denial of service). (CVE-2010-1188, Important)

This update also adds the following enhancement :

* kernel support for the iptables connlimit module. This module can be used to help mitigate some types of denial of service attacks. Note:
This update alone does not address connlimit support. A future iptables package update will allow connlimit to work correctly.
(BZ#563222)

Users should upgrade to these updated packages, which contain backported patches to correct this issue and add this enhancement. The system must be rebooted for this update to take effect.

From Red Hat Security Advisory 2010:0394 :

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security fixes :

* RHSA-2009:1024 introduced a flaw in the ptrace implementation on Itanium systems. ptrace_check_attach() was not called during certain ptrace() requests. Under certain circumstances, a local, unprivileged user could use this flaw to call ptrace() on a process they do not own, giving them control over that process. (CVE-2010-0729, Important)

* a flaw was found in the kernel's Unidirectional Lightweight Encapsulation (ULE) implementation. A remote attacker could send a specially crafted ISO MPEG-2 Transport Stream (TS) frame to a target system, resulting in a denial of service. (CVE-2010-1086, Important)

* a use-after-free flaw was found in tcp_rcv_state_process() in the kernel's TCP/IP protocol suite implementation. If a system using IPv6 had the IPV6_RECVPKTINFO option set on a listening socket, a remote attacker could send an IPv6 packet to that system, causing a kernel panic. (CVE-2010-1188, Important)

* a divide-by-zero flaw was found in azx_position_ok() in the Intel High Definition Audio driver, snd-hda-intel. A local, unprivileged user could trigger this flaw to cause a denial of service.
(CVE-2010-1085, Moderate)

* an information leak flaw was found in the kernel's USB implementation. Certain USB errors could result in an uninitialized kernel buffer being sent to user-space. An attacker with physical access to a target system could use this flaw to cause an information leak. (CVE-2010-1083, Low)

Red Hat would like to thank Ang Way Chuang for reporting CVE-2010-1086.

Bug fixes :

* a regression prevented the Broadcom BCM5761 network device from working when in the first (top) PCI-E slot of Hewlett-Packard (HP) Z600 systems. Note: The card worked in the 2nd or 3rd PCI-E slot.
(BZ#567205)

* the Xen hypervisor supports 168 GB of RAM for 32-bit guests. The physical address range was set incorrectly, however, causing 32-bit, para-virtualized Red Hat Enterprise Linux 4.8 guests to crash when launched on AMD64 or Intel 64 hosts that have more than 64 GB of RAM.
(BZ#574392)

* RHSA-2009:1024 introduced a regression, causing diskdump to fail on systems with certain adapters using the qla2xxx driver. (BZ#577234)

* a race condition caused TX to stop in a guest using the virtio_net driver. (BZ#580089)

* on some systems, using the 'arp_validate=3' bonding option caused both links to show as 'down' even though the arp_target was responding to ARP requests sent by the bonding driver. (BZ#580842)

* in some circumstances, when a Red Hat Enterprise Linux client connected to a re-booted Windows-based NFS server, server-side filehandle-to-inode mapping changes caused a kernel panic.
'bad_inode_ops' handling was changed to prevent this. Note:
filehandle-to-inode mapping changes may still cause errors, but not panics. (BZ#582908)

* when installing a Red Hat Enterprise Linux 4 guest via PXE, hard-coded fixed-size scatterlists could conflict with host requests, causing the guest's kernel to panic. With this update, dynamically allocated scatterlists are used, resolving this issue. (BZ#582911)

Enhancements :

* kernel support for connlimit. Note: iptables errata update RHBA-2010:0395 is also required for connlimit to work correctly.
(BZ#563223)

* support for the Intel architectural performance monitoring subsystem (arch_perfmon). On supported CPUs, arch_perfmon offers means to mark performance events and options for configuring and counting these events. (BZ#582913)

* kernel support for OProfile sampling of Intel microarchitecture (Nehalem) CPUs. This update alone does not address OProfile support for such CPUs. A future oprofile package update will allow OProfile to work on Intel Nehalem CPUs. (BZ#582241)

Users should upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements.
The system must be rebooted for this update to take effect.
