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

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

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2010-2492     Andre Osterhues reported an issue in the eCryptfs     subsystem. A buffer overflow condition may allow local     users to cause a denial of service or gain elevated     privileges.

  - CVE-2010-2954     Tavis Ormandy reported an issue in the irda subsystem     which may allow local users to cause a denial of service     via a NULL pointer dereference.

  - CVE-2010-3078     Dan Rosenberg discovered an issue in the XFS file system     that allows local users to read potentially sensitive     kernel memory.

  - CVE-2010-3080     Tavis Ormandy reported an issue in the ALSA sequencer     OSS emulation layer. Local users with sufficient     privileges to open /dev/sequencer (by default on Debian,     this is members of the 'audio' group) can cause a denial     of service via a NULL pointer dereference.

  - CVE-2010-3081     Ben Hawkes discovered an issue in the 32-bit     compatibility code for 64-bit systems. Local users can     gain elevated privileges due to insufficient checks in     compat_alloc_user_space allocations.

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 components and libraries :

  - Apache Tomcat 
  - Apache Tomcat Manager
  - cURL 
  - Java Runtime Environment (JRE)
  - Kernel 
  - Microsoft SQL Express
  - OpenSSL
  - pam_krb5

CVE-2010-2066: The mext_check_arguments function in fs/ext4/move_extent.c in the Linux kernel allowed local users to overwrite an append-only file via a MOVE_EXT ioctl call that specifies this file as a donor.

CVE-2010-2495: The pppol2tp_xmit function in drivers/net/pppol2tp.c in the L2TP implementation in the Linux kernel did not properly validate certain values associated with an interface, which allowed attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via vectors related to a routing change.

CVE-2010-2071: The btrfs_xattr_set_acl function in fs/btrfs/acl.c in btrfs in the Linux kernel did not check file ownership before setting an ACL, which allowed local users to bypass file permissions by setting arbitrary ACLs, as demonstrated using setfacl.

CVE-2010-1641: The do_gfs2_set_flags function in fs/gfs2/file.c in the Linux kernel did not verify the ownership of a file, which allowed local users to bypass intended access restrictions via a SETFLAGS ioctl request.

CVE-2010-1087: The nfs_wait_on_request function in fs/nfs/pagelist.c in Linux kernel 2.6.x allowed attackers to cause a denial of service (Oops) via unknown vectors related to truncating a file and an operation that is not interruptible.

CVE-2010-1636: The btrfs_ioctl_clone function in fs/btrfs/ioctl.c in the btrfs functionality in the Linux kernel did not ensure that a cloned file descriptor has been opened for reading, which allowed local users to read sensitive information from a write-only file descriptor.

CVE-2010-1437: Race condition in the find_keyring_by_name function in security/keys/keyring.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via keyctl session commands that trigger access to a dead keyring that is undergoing deletion by the key_cleanup function.

CVE-2010-1148: The cifs_create function in fs/cifs/dir.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a NULL nameidata (aka nd) field in a POSIX file-creation request to a server that supports UNIX extensions.

CVE-2010-1162: The release_one_tty function in drivers/char/tty_io.c in the Linux kernel omitted certain required calls to the put_pid function, which has unspecified impact and local attack vectors.

CVE-2010-1146: The Linux kernel, when a ReiserFS filesystem exists, did not restrict read or write access to the .reiserfs_priv directory, which allowed local users to gain privileges by modifying (1) extended attributes or (2) ACLs, as demonstrated by deleting a file under .reiserfs_priv/xattrs/.

CVE-2009-4537: drivers/net/r8169.c in the r8169 driver in the Linux kernel did not properly check the size of an Ethernet frame that exceeds the MTU, which allowed remote attackers to (1) cause a denial of service (temporary network outage) via a packet with a crafted size, in conjunction with certain packets containing A characters and certain packets containing E characters; or (2) cause a denial of service (system crash) via a packet with a crafted size, in conjunction with certain packets containing '\0' characters, related to the value of the status register and erroneous behavior associated with the RxMaxSize register. NOTE: this vulnerability exists because of an incorrect fix for CVE-2009-1389.

a. Service Console OS update for COS kernel package.

   This patch updates the Service Console kernel to fix a stack    pointer underflow issue in the 32-bit compatibility layer.

   Exploitation of this issue could allow a local user to gain    additional privileges.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2010-3081 to this issue.

A vulnerability was discovered and corrected in the Linux 2.6 kernel :

The compat_alloc_user_space functions in include/asm/compat.h files in the Linux kernel before 2.6.36-rc4-git2 on 64-bit platforms do not properly allocate the userspace memory required for the 32-bit compatibility layer, which allows local users to gain privileges by leveraging the ability of the compat_mc_getsockopt function (aka the MCAST_MSFILTER getsockopt support) to control a certain length value, related to a stack pointer underflow issue, as exploited in the wild in September 2010. (CVE-2010-3081)

The IA32 system call emulation functionality in arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.36-rc4-git2 on the x86_64 platform does not zero extend the %eax register after the 32-bit entry path to ptrace is used, which allows local users to gain privileges by triggering an out-of-bounds access to the system call table using the %rax register. NOTE: this vulnerability exists because of a CVE-2007-4573 regression. (CVE-2010-3301)

Integer overflow in the ext4_ext_get_blocks function in fs/ext4/extents.c in the Linux kernel before 2.6.34 allows local users to cause a denial of service (BUG and system crash) via a write operation on the last block of a large file, followed by a sync operation. (CVE-2010-3015)

Additionally, the kernel has been updated to the stable version 2.6.31.14. A timeout bug in bnx2 has been fixed. Muting and unmuting on VT1812/VT2002P now should work correctly. A fix for ACL decoding on NFS was added. Rebooting on Dell Precision WorkStation T7400 was corrected. Read balancing with RAID0 and RAID1 on drives larger then 2TB was also fixed. A more detailed description is available in the package changelog and related tickets.

Mismatch between 32bit and 64bit register usage in the system call entry path could be used by local attackers to gain root privileges.
This problem only affects x86_64 kernels.

CVE-2010-3081: Incorrect buffer handling in the biarch-compat buffer handling could be used by local attackers to gain root privileges.
This problem affects foremost x86_64, or potentially other biarch platforms, like PowerPC and S390x.

CVE-2010-3084: A buffer overflow in the ETHTOOL_GRXCLSRLALL code could be used to crash the kernel or potentially execute code.

CVE-2010-2955: A kernel information leak via the WEXT ioctl was fixed.

CVE-2010-2960: The keyctl_session_to_parent function in security/keys/keyctl.c in the Linux kernel expects that a certain parent session keyring exists, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function.

CVE-2010-3080: A double free in an alsa error path was fixed, which could lead to kernel crashes.

CVE-2010-3079: Fixed a ftrace NULL pointer dereference problem which could lead to kernel crashes.

CVE-2010-3298: Fixed a kernel information leak in the net/usb/hso driver.

CVE-2010-3296: Fixed a kernel information leak in the cxgb3 driver.

CVE-2010-3297: Fixed a kernel information leak in the net/eql driver.

The remote MiracleLinux 3 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2010-456:15 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-2010-3081     The compat_alloc_user_space() function in the Linux kernel 32/64-bit compatibility layer implementation     was missing sanity checks. On 64 bits systems, a normal local user could abuse this flaw to escalate their     privileges.

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.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2011-47:01 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of your Asianux 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-2009-3080     Array index error in the gdth_read_event function in drivers/scsi/gdth.c in the Linux kernel before     2.6.32-rc8 allows local users to cause a denial of service or possibly gain privileges via a negative     event index in an IOCTL request.
    CVE-2009-3620     The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify     Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of     service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl     calls.
    CVE-2009-4536     drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel 2.6.32.3 and earlier handles     Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete     frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload.
    NOTE: this vulnerability exists because of an incorrect fix for CVE-2009-1385.
    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.
    CVE-2010-2240     The do_anonymous_page function in mm/memory.c in the Linux kernel before 2.6.27.52, 2.6.32.x before     2.6.32.19, 2.6.34.x before 2.6.34.4, and 2.6.35.x before 2.6.35.2 does not properly separate the stack and     the heap, which allows context-dependent attackers to execute arbitrary code by writing to the bottom page     of a shared memory segment, as demonstrated by a memory-exhaustion attack against the X.Org X server.
    CVE-2010-3081     The compat_alloc_user_space functions in include/asm/compat.h files in the Linux kernel before     2.6.36-rc4-git2 on 64-bit platforms do not properly allocate the userspace memory required for the 32-bit     compatibility layer, which allows local users to gain privileges by leveraging the ability of the     compat_mc_getsockopt function (aka the MCAST_MSFILTER getsockopt support) to control a certain length     value, related to a 'stack pointer underflow' issue, as exploited in the wild in September 2010.

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