The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2011-264:04 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-2011-0726     The do_task_stat function in fs/proc/array.c in the Linux kernel before 2.6.39-rc1 does not perform an     expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by     reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE     binary.
    CVE-2011-1093     The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP)     implementation in the Linux kernel before 2.6.38 does not properly handle packets for a CLOSED endpoint,     which allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending     a DCCP-Close packet followed by a DCCP-Reset packet.
    CVE-2011-1170     net/ipv4/netfilter/arp_tables.c in the IPv4 implementation in the Linux kernel before 2.6.39 does not     place the expected '0' character at the end of string data in the values of certain structure members,     which allows local users to obtain potentially sensitive information from kernel memory by leveraging the     CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting     modprobe process.
    CVE-2011-1171     net/ipv4/netfilter/ip_tables.c in the IPv4 implementation in the Linux kernel before 2.6.39 does not place     the expected '0' character at the end of string data in the values of certain structure members, which     allows local users to obtain potentially sensitive information from kernel memory by leveraging the     CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting     modprobe process.
    CVE-2011-1172     net/ipv6/netfilter/ip6_tables.c in the IPv6 implementation in the Linux kernel before 2.6.39 does not     place the expected '0' character at the end of string data in the values of certain structure members,     which allows local users to obtain potentially sensitive information from kernel memory by leveraging the     CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting     modprobe process.
    CVE-2011-1163     The osf_partition function in fs/partitions/osf.c in the Linux kernel before 2.6.38 does not properly     handle an invalid number of partitions, which might allow local users to obtain potentially sensitive     information from kernel heap memory via vectors related to partition-table parsing.
    CVE-2011-1494     Integer overflow in the _ctl_do_mpt_command function in drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux     kernel 2.6.38 and earlier might allow local users to gain privileges or cause a denial of service (memory     corruption) via an ioctl call specifying a crafted value that triggers a heap-based buffer overflow.
    CVE-2011-1495     drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel 2.6.38 and earlier does not validate (1) length and     (2) offset values before performing memory copy operations, which might allow local users to gain     privileges, cause a denial of service (memory corruption), or obtain sensitive information from kernel     memory via a crafted ioctl call, related to the _ctl_do_mpt_command and _ctl_diag_read_buffer functions.
    CVE-2011-1577     Heap-based buffer overflow in the is_gpt_valid function in fs/partitions/efi.c in the Linux kernel 2.6.38     and earlier allows physically proximate attackers to cause a denial of service (OOPS) or possibly have     unspecified other impact via a crafted size of the EFI GUID partition-table header on removable media.

The remote VMware ESX / ESXi host is missing a security-related patch.
It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities, in several third-party libraries :

  - COS kernel
  - cURL
  - python
  - rpm

The SUSE Linux Enterprise 11 Service Pack 1 kernel was updated to 2.6.32.43 and fixes various bugs and security issues.

The following security issues were fixed :

  - The normal mmap paths all avoid creating a mapping where     the pgoff inside the mapping could wrap around due to     overflow. However, an expanding mremap() can take such a     non-wrapping mapping and make it bigger and cause a     wrapping condition. (CVE-2011-2496)

  - A local unprivileged user able to access a NFS     filesystem could use file locking to deadlock parts of     an nfs server under some circumstance. (CVE-2011-2491)

  - Fixed a race between ksmd and other memory management     code, which could result in a NULL ptr dereference and     kernel crash. (CVE-2011-2183)

  - In both trigger_scan and sched_scan operations, we were     checking for the SSID length before assigning the value     correctly. Since the memory was just kzalloced, the     check was always failing and SSID with over 32     characters were allowed to go through. This required     CAP_NET_ADMIN privileges to be exploited.
    (CVE-2011-2517)

  - A malicious user or buggy application could inject     diagnosing byte code and trigger an infinite loop in     inet_diag_bc_audit(). (CVE-2011-2213)

  - The code for evaluating LDM partitions (in     fs/partitions/ldm.c) contained bugs that could crash the     kernel for certain corrupted LDM partitions.
    (CVE-2011-1017 / CVE-2011-1012 / CVE-2011-2182)

  - Multiple integer overflows in the next_pidmap function     in kernel/pid.c in the Linux kernel allowed local users     to cause a denial of service (system crash) via a     crafted (1) getdents or (2) readdir system call.
    (CVE-2011-1593)

  - The proc filesystem implementation in the Linux kernel     did not restrict access to the /proc directory tree of a     process after this process performs an exec of a setuid     program, which allowed local users to obtain sensitive     information or cause a denial of service via open,     lseek, read, and write system calls. (CVE-2011-1020)

  - When using a setuid root mount.cifs, local users could     hijack password protected mounted CIFS shares of other     local users. (CVE-2011-1585)

  - Kernel information via the TPM devices could by used by     local attackers to read kernel memory. (CVE-2011-1160)

  - The Linux kernel automatically evaluated partition     tables of storage devices. The code for evaluating EFI     GUID partitions (in fs/partitions/efi.c) contained a bug     that causes a kernel oops on certain corrupted GUID     partition tables, which might be used by local attackers     to crash the kernel or potentially execute code.
    (CVE-2011-1577)

  - In a bluetooth ioctl, struct sco_conninfo has one     padding byte in the end. Local variable cinfo of type     sco_conninfo was copied to userspace with this     uninizialized one byte, leading to an old stack contents     leak. (CVE-2011-1078)

  - In a bluetooth ioctl, struct ca is copied from     userspace. It was not checked whether the 'device' field     was NULL terminated. This potentially leads to BUG()     inside of alloc_netdev_mqs() and/or information leak by     creating a device with a name made of contents of kernel     stack. (CVE-2011-1079)

  - In ebtables rule loading, struct tmp is copied from     userspace. It was not checked whether the 'name' field     is NULL terminated. This may have lead to buffer     overflow and passing contents of kernel stack as a     module name to try_then_request_module() and,     consequently, to modprobe commandline. It would be seen     by all userspace processes. (CVE-2011-1080)

  - The econet_sendmsg function in net/econet/af_econet.c in     the Linux kernel on the x86_64 platform allowed remote     attackers to obtain potentially sensitive information     from kernel stack memory by reading uninitialized data     in the ah field of an Acorn Universal Networking (AUN)     packet. (CVE-2011-1173)

  - net/ipv4/netfilter/arp_tables.c in the IPv4     implementation in the Linux kernel did not place the     expected '0' character at the end of string data in the     values of certain structure members, which allowed local     users to obtain potentially sensitive information from     kernel memory by leveraging the CAP_NET_ADMIN capability     to issue a crafted request, and then reading the     argument to the resulting modprobe process.
    (CVE-2011-1170)

  - net/ipv4/netfilter/ip_tables.c in the IPv4     implementation in the Linux kernel did not place the     expected '0' character at the end of string data in the     values of certain structure members, which allowed local     users to obtain potentially sensitive information from     kernel memory by leveraging the CAP_NET_ADMIN capability     to issue a crafted request, and then reading the     argument to the resulting modprobe process.
    (CVE-2011-1171)

  - net/ipv6/netfilter/ip6_tables.c in the IPv6     implementation in the Linux kernel did not place the     expected '0' character at the end of string data in the     values of certain structure members, which allowed local     users to obtain potentially sensitive information from     kernel memory by leveraging the CAP_NET_ADMIN capability     to issue a crafted request, and then reading the     argument to the resulting modprobe process.
    (CVE-2011-1172)

  - Multiple integer overflows in the (1)     agp_allocate_memory and (2) agp_create_user_memory     functions in drivers/char/agp/generic.c in the Linux     kernel before allowed local users to trigger buffer     overflows, and consequently cause a denial of service     (system crash) or possibly have unspecified other     impact, via vectors related to calls that specify a     large number of memory pages. (CVE-2011-1746)

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This kernel update for the SUSE Linux Enterprise 10 SP4 kernel fixes several security issues and bugs.

The following security issues were fixed :

  - The code for evaluating LDM partitions (in     fs/partitions/ldm.c) contained bugs that could crash the     kernel for certain corrupted LDM partitions.
    (CVE-2011-1017 / CVE-2011-1012)

  - Boundschecking was missing in AARESOLVE_OFFSET, which     allowed local attackers to overwrite kernel memory and     so escalate privileges or crash the kernel.
    (CVE-2011-1573)

  - When using a setuid root mount.cifs, local users could     hijack password protected mounted CIFS shares of other     local users. (CVE-2011-1585)

  - Kernel information via the TPM devices could by used by     local attackers to read kernel memory. (CVE-2011-1160)

  - The Linux kernel automatically evaluated partition     tables of storage devices. The code for evaluating EFI     GUID partitions (in fs/partitions/efi.c) contained a bug     that causes a kernel oops on certain corrupted GUID     partition tables, which might be used by local attackers     to crash the kernel or potentially execute code.
    (CVE-2011-1577)

  - In the IrDA module, length fields provided by a peer for     names and attributes may be longer than the destination     array sizes and were not checked, this allowed local     attackers (close to the irda port) to potentially     corrupt memory. (CVE-2011-1180)

  - A system out of memory condition (denial of service)     could be triggered with a large socket backlog,     exploitable by local users. This has been addressed by     backlog limiting. (CVE-2010-4251)

  - The Radeon GPU drivers in the Linux kernel did not     properly validate data related to the AA resolve     registers, which allowed local users to write to     arbitrary memory locations associated with (1) Video RAM     (aka VRAM) or (2) the Graphics Translation Table (GTT)     via crafted values. (CVE-2011-1016)

  - When parsing the FAC_NATIONAL_DIGIS facilities field, it     was possible for a remote host to provide more     digipeaters than expected, resulting in heap corruption.
    (CVE-2011-1493)

  - Local attackers could send signals to their programs     that looked like coming from the kernel, potentially     gaining privileges in the context of setuid programs.
    (CVE-2011-1182)

  - The code for evaluating Mac partitions (in     fs/partitions/mac.c) contained a bug that could crash     the kernel for certain corrupted Mac partitions.
    (CVE-2011-1010)

  - The code for evaluating OSF partitions (in     fs/partitions/osf.c) contained a bug that leaks data     from kernel heap memory to userspace for certain     corrupted OSF partitions. (CVE-2011-1163)

  - Specially crafted requests may be written to     /dev/sequencer resulting in an underflow when     calculating a size for a copy_from_user() operation in     the driver for MIDI interfaces. On x86, this just     returns an error, but it could have caused memory     corruption on other architectures. Other malformed     requests could have resulted in the use of uninitialized     variables. (CVE-2011-1476)

  - Due to a failure to validate user-supplied indexes in     the driver for Yamaha YM3812 and OPL-3 chips, a     specially crafted ioctl request could have been sent to     /dev/sequencer, resulting in reading and writing beyond     the bounds of heap buffers, and potentially allowing     privilege escalation. (CVE-2011-1477)

  - A information leak in the XFS geometry calls could be     used by local attackers to gain access to kernel     information. (CVE-2011-0191)

  - The sctp_rcv_ootb function in the SCTP implementation in     the Linux kernel allowed remote attackers to cause a     denial of service (infinite loop) via (1) an Out Of The     Blue (OOTB) chunk or (2) a chunk of zero length.
    (CVE-2010-0008)
