Security fixes :

  - A race condition in the way asynchronous I/O and     fallocate() interacted when using ext4 could allow a     local, unprivileged user to obtain random data from a     deleted file. (CVE-2012-4508, Important)

  - A flaw in the way the Xen hypervisor implementation     range checked guest provided addresses in the     XENMEM_exchange hypercall could allow a malicious,     para-virtualized guest administrator to crash the     hypervisor or, potentially, escalate their privileges,     allowing them to execute arbitrary code at the     hypervisor level. (CVE-2012-5513, Important)

  - A flaw in the Reliable Datagram Sockets (RDS) protocol     implementation could allow a local, unprivileged user to     cause a denial of service. (CVE-2012-2372, Moderate)

  - A race condition in the way access to inet->opt     ip_options was synchronized in the Linux kernel's TCP/IP     protocol suite implementation. Depending on the network     facing applications running on the system, a remote     attacker could possibly trigger this flaw to cause a     denial of service. A local, unprivileged user could use     this flaw to cause a denial of service regardless of the     applications the system runs. (CVE-2012-3552, Moderate)

  - The Xen hypervisor implementation did not properly     restrict the period values used to initialize per VCPU     periodic timers. A privileged guest user could cause an     infinite loop on the physical CPU. If the watchdog were     enabled, it would detect said loop and panic the host     system. (CVE-2012-4535, Moderate)

  - A flaw in the way the Xen hypervisor implementation     handled set_p2m_entry() error conditions could allow a     privileged, fully-virtualized guest user to crash the     hypervisor. (CVE-2012-4537, Moderate)

Bug fixes :

  - Previously, the interrupt handlers of the qla2xxx driver     could clear pending interrupts right after the IRQ lines     were attached during system start-up. Consequently, the     kernel could miss the interrupt that reported completion     of the link initialization, and the qla2xxx driver then     failed to detect all attached LUNs. With this update,     the qla2xxx driver has been modified to no longer clear     interrupt bits after attaching the IRQ lines. The driver     now correctly detects all attached LUNs as expected.

  - The Ethernet channel bonding driver reported the MII     (Media Independent Interface) status of the bond     interface in 802.3ad mode as being up even though the     MII status of all of the slave devices was down. This     could pose a problem if the MII status of the bond     interface was used to determine if failover should     occur. With this update, the agg_device_up() function     has been added to the bonding driver, which allows the     driver to report the link status of the bond interface     correctly, that is, down when all of its slaves are     down, in the 802.3ad mode.

Enhancements :

  - This update backports several changes from the latest     upstream version of the bnx2x driver. The most important     change, the remote-fault link detection feature, allows     the driver to periodically scan the physical link layer     for remote faults. If the physical link appears to be up     and a fault is detected, the driver indicates that the     link is down. When the fault is cleared, the driver     indicates that the link is up again.

  - The INET socket interface has been modified to send a     warning message when the ip_options structure is     allocated directly by a third-party module using the     kmalloc() function.

The system must be rebooted for this update to take effect.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2013-80:01 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel     handles the basic functions of the operating system: memory allocation, process allocation, device input     and output, etc.
    Security issues fixed with this release:
     CVE-2012-2372     The rds_ib_xmit function in net/rds/ib_send.c in the Reliable Datagram Sockets (RDS) protocol     implementation in the Linux kernel 3.7.4 and earlier allows local users to cause a denial of service     (BUG_ON and kernel panic) by establishing an RDS connection with the source IP address equal to the IPoIB     interface's own IP address, as demonstrated by rds-ping.
     CVE-2012-3552     The IP implementation in the Linux kernel before 3.0 might allow remote attackers to cause a denial of     service (slab corruption and system crash) by sending packets to an application that sets socket options     during the handling of network traffic.
     CVE-2012-4508     Race condition in fs/ext4/extents.c in the Linux kernel before 3.4.16 allows local users to obtain     sensitive information from a deleted file by reading an extent that was not properly marked as     uninitialized.
     CVE-2012-4535     Xen 3.4 through 4.2, and possibly earlier versions, allows local guest OS administrators to cause a denial     of service (Xen infinite loop and physical CPU consumption) by setting a VCPU with an inappropriate     deadline.
     CVE-2012-4537     Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables     when the set_p2m_entry function fails, which allows local HVM guest OS administrators to cause a denial of     service (memory consumption and assertion failure), aka Memory mapping failure DoS vulnerability.
     CVE-2012-5513     The XENMEM_exchange handler in Xen 4.2 and earlier does not properly check the memory address, which     allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges     via unspecified vectors that overwrite memory in the hypervisor reserved range.
    Fixed bugs:
     Modified the qla2xxx driver so that it now correctly detects all attached LUNs.
     The Media Independent Interfacestatus of the bond interface in 802.3ad appeared as up even when MII     status of all of the slave devices was down. This has been fixed.
    Enhancements:
     Backported many changes from the bnx2x driver upstream version, in particular, the remote-fault link     detection feature.
     The INET socket interface now sends a warning when a third-party module using the kmalloc() function     allocates the ip_options structure.
    Please also check the changelog for extensive details.

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

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