Summary

The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to "return the same value over and over again for long stretches of time."

    NASL idSUSE_11_0_KERNEL-100203.NASL
    descriptionThis kernel update for openSUSE 11.0 fixes some bugs and several security problems. The following security issues are fixed: CVE-2009-4536: drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel 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. CVE-2009-4538: drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets. CVE-2010-0007: Missing CAP_NET_ADMIN checks in the ebtables netfilter code might have allowed local attackers to modify bridge firewall settings. CVE-2010-0003: An information leakage on fatal signals on x86_64 machines was fixed. CVE-2009-4138: drivers/firewire/ohci.c in the Linux kernel, when packet-per-buffer mode is used, allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unknown other impact via an unspecified ioctl associated with receiving an ISO packet that contains zero in the payload-length field. CVE-2009-4308: The ext4_decode_error function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference), and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal. CVE-2009-3939: The poll_mode_io file for the megaraid_sas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file. CVE-2009-4021: The fuse_direct_io function in fs/fuse/file.c in the fuse subsystem in the Linux kernel before 2.6.32-rc7 might allow attackers to cause a denial of service (invalid pointer dereference and OOPS) via vectors possibly related to a memory-consumption attack. CVE-2009-3547: A race condition in the pipe(2) systemcall could be used by local attackers to hang the machine. The kernel in Moblin 2.0 uses NULL ptr protection which avoids code execution possbilities. CVE-2009-2903: Memory leak in the appletalk subsystem in the Linux kernel 2.4.x through 2.4.37.6 and 2.6.x through 2.6.31, when the appletalk and ipddp modules are loaded but the ipddp

    The following security issues are fixed: CVE-2009-4536:
    drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel
    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.
    
    CVE-2009-4538: drivers/net/e1000e/netdev.c in the e1000e driver in the
    Linux kernel does not properly check the size of an Ethernet frame
    that exceeds the MTU, which allows remote attackers to have an
    unspecified impact via crafted packets.
    
    CVE-2010-0007: Missing CAP_NET_ADMIN checks in the ebtables netfilter
    code might have allowed local attackers to modify bridge firewall
    settings.
    
    CVE-2010-0003: An information leakage on fatal signals on x86_64
    machines was fixed.
    
    CVE-2009-4138: drivers/firewire/ohci.c in the Linux kernel, when
    packet-per-buffer mode is used, allows local users to cause a denial
    of service (NULL pointer dereference and system crash) or possibly
    have unknown other impact via an unspecified ioctl associated with
    receiving an ISO packet that contains zero in the payload-length
    field.
    
    CVE-2009-4308: The ext4_decode_error function in fs/ext4/super.c in
    the ext4 filesystem in the Linux kernel before 2.6.32 allows
    user-assisted remote attackers to cause a denial of service (NULL
    pointer dereference), and possibly have unspecified other impact, via
    a crafted read-only filesystem that lacks a journal.
    
    CVE-2009-3939: The poll_mode_io file for the megaraid_sas driver in
    the Linux kernel 2.6.31.6 and earlier has world-writable permissions,
    which allows local users to change the I/O mode of the driver by
    modifying this file.
    
    CVE-2009-4021: The fuse_direct_io function in fs/fuse/file.c in the
    fuse subsystem in the Linux kernel before 2.6.32-rc7 might allow
    attackers to cause a denial of service (invalid pointer dereference
    and OOPS) via vectors possibly related to a memory-consumption attack.
    
    CVE-2009-3547: A race condition in the pipe(2) systemcall could be
    used by local attackers to hang the machine. The kernel in Moblin 2.0
    uses NULL ptr protection which avoids code execution possbilities.
    
    CVE-2009-2903: Memory leak in the appletalk subsystem in the Linux
    kernel 2.4.x through 2.4.37.6 and 2.6.x through 2.6.31, when the
    appletalk and ipddp modules are loaded but the ipddp'N' device is not
    found, allows remote attackers to cause a denial of service (memory
    consumption) via IP-DDP datagrams.
    
    CVE-2009-3621: net/unix/af_unix.c in the Linux kernel 2.6.31.4 and
    earlier allows local users to cause a denial of service (system hang)
    by creating an abstract-namespace AF_UNIX listening socket, performing
    a shutdown operation on this socket, and then performing a series of
    connect operations to this socket.
    
    CVE-2009-3612: The tcf_fill_node function in net/sched/cls_api.c in
    the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and
    2.4.37.6 and earlier, does not initialize a certain tcm__pad2
    structure member, which might allow local users to obtain sensitive
    information from kernel memory via unspecified vectors.
    
    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-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the
    NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS
    servers to cause a denial of service (NULL pointer dereference and
    panic) by sending a certain response containing incorrect file
    attributes, which trigger attempted use of an open file that lacks
    NFSv4 state.
    
    CVE-2009-3286: NFSv4 in the Linux kernel 2.6.18, and possibly other
    versions, does not properly clean up an inode when an O_EXCL create
    fails, which causes files to be created with insecure settings such as
    setuid bits, and possibly allows local users to gain privileges,
    related to the execution of the do_open_permission function even when
    a create fails.
    
    CVE-2009-2910: arch/x86/ia32/ia32entry.S in the Linux kernel before
    2.6.31.4 on the x86_64 platform does not clear certain kernel
    registers before a return to user mode, which allows local users to
    read register values from an earlier process by switching an ia32
    process to 64-bit mode.
    
    CVE-2009-3238: The get_random_int function in drivers/char/random.c in
    the Linux kernel before 2.6.30 produces insufficiently random numbers,
    which allows attackers to predict the return value, and possibly
    defeat protection mechanisms based on randomization, via vectors that
    leverage the function's tendency to 'return the same value over and
    over again for long stretches of time.'
    
    CVE-2009-2848: The execve function in the Linux kernel, possibly
    2.6.30-rc6 and earlier, does not properly clear the
    current->clear_child_tid pointer, which allows local users to cause a
    denial of service (memory corruption) or possibly gain privileges via
    a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID
    enabled, which is not properly handled during thread creation and
    exit.
    
    CVE-2009-3002: The Linux kernel before 2.6.31-rc7 does not initialize
    certain data structures within getname functions, which allows local
    users to read the contents of some kernel memory locations by calling
    getsockname on (1) an AF_APPLETALK socket, related to the
    atalk_getname function in net/appletalk/ddp.c; (2) an AF_IRDA socket,
    related to the irda_getname function in net/irda/af_irda.c; (3) an
    AF_ECONET socket, related to the econet_getname function in
    net/econet/af_econet.c; (4) an AF_NETROM socket, related to the
    nr_getname function in net/netrom/af_netrom.c; (5) an AF_ROSE socket,
    related to the rose_getname function in net/rose/af_rose.c; or (6) a
    raw CAN socket, related to the raw_getname function in net/can/raw.c.
    
    CVE-2009-1633: Multiple buffer overflows in the cifs subsystem in the
    Linux kernel before 2.6.29.4 allow remote CIFS servers to cause a
    denial of service (memory corruption) and possibly have unspecified
    other impact via (1) a malformed Unicode string, related to Unicode
    string area alignment in fs/cifs/sess.c; or (2) long Unicode
    characters, related to fs/cifs/cifssmb.c and the cifs_readdir function
    in fs/cifs/readdir.c."

The following security issues were fixed: CVE-2009-3547: A race condition during pipe open could be used by local attackers to elevate privileges. - On x86_64 systems a information leak of high register contents (upper 32bit) was fixed. (CVE-2009-2910) - The randomness of the ASLR methods used in the kernel was increased. (CVE-2009-3238) - A information leak from the kernel due to uninitialized memory in AGP handling was fixed. (CVE-2009-1192) - A signed comparison in the ax25 sockopt handler was fixed which could be used to crash the kernel or potentially execute code. (CVE-2009-2909) - The execve function in the Linux kernel did not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit. (CVE-2009-2848) - Fixed various sockethandler getname leaks, which could disclose memory previously used by the kernel or other userland processes to the local attacker. (CVE-2009-3002) - Multiple buffer overflows in the cifs subsystem in the Linux kernel allow remote CIFS servers to cause a denial of service (memory corruption) and possibly have unspecified other impact via (1) a malformed Unicode string, related to Unicode string area alignment in fs/cifs/sess.c; or (2) long Unicode characters, related to fs/cifs/cifssmb.c and the cifs_readdir function in fs/cifs/readdir.c.

    descriptionThis update fixes various bugs and some security issues in the SUSE Linux Enterprise 10 SP 3 kernel. The following security issues were fixed: CVE-2009-3238: The get_random_int function in drivers/char/random.c in the Linux kernel produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the functions tendency to return the same value over and over again for long stretches of time. - The (1) agp_generic_alloc_page and (2) agp_generic_alloc_pages functions in drivers/char/agp/generic.c in the agp subsystem in the Linux kernel do not zero out pages that may later be available to a user-space process, which allows local users to obtain sensitive information by reading these pages. (CVE-2009-1192) - Unsigned check in the ax25 socket handler could allow local attackers to potentially crash the kernel or even execute code. (CVE-2009-2909)

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, sensitive memory leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-2846 Michael Buesch noticed a typing issue in the eisa-eeprom driver for the hppa architecture. Local users could exploit this issue to gain access to restricted memory. - CVE-2009-2847 Ulrich Drepper noticed an issue in the do_sigalstack routine on 64-bit systems. This issue allows local users to gain access to potentially sensitive memory on the kernel stack. - CVE-2009-2848 Eric Dumazet discovered an issue in the execve path, where the clear_child_tid variable was not being properly cleared. Local users could exploit this issue to cause a denial of service (memory corruption). - CVE-2009-2849 Neil Brown discovered an issue in the sysfs interface to md devices. When md arrays are not active, local users can exploit this vulnerability to cause a denial of service (oops). - CVE-2009-2903 Mark Smith discovered a memory leak in the appletalk implementation.

    descriptionFrom Red Hat Security Advisory 2009:1438 : Updated kernel packages that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2009-1895, Important) * it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important) * Solar Designer reported a missing capability check in the z90crypt driver in the Linux kernel. This missing check could allow a local user with an effective user ID (euid) of 0 to bypass intended capability restrictions. (CVE-2009-1883, Moderate) * a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak. (CVE-2009-2847, Moderate) This update also fixes the following bugs : * the gcc flag

    descriptionUpdated kernel packages that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes : * several flaws were found in the way the Linux kernel CIFS implementation handles Unicode strings. CIFS clients convert Unicode strings sent by a server to their local character sets, and then write those strings into memory. If a malicious server sent a long enough string, it could write past the end of the target memory region and corrupt other memory areas, possibly leading to a denial of service or privilege escalation on the client mounting the CIFS share. (CVE-2009-1439, CVE-2009-1633, Important) * the Linux kernel Network File System daemon (nfsd) implementation did not drop the CAP_MKNOD capability when handling requests from local, unprivileged users. This flaw could possibly lead to an information leak or privilege escalation. (CVE-2009-1072, Moderate) * Frank Filz reported the NFSv4 client was missing a file permission check for the execute bit in some situations. This could allow local, unprivileged users to run non-executable files on NFSv4 mounted file systems. (CVE-2009-1630, Moderate) * a missing check was found in the hypervisor_callback() function in the Linux kernel provided by the kernel-xen package. This could cause a denial of service of a 32-bit guest if an application running in that guest accesses a certain memory location in the kernel. (CVE-2009-1758, Moderate) * a flaw was found in the AGPGART driver. The agp_generic_alloc_page() and agp_generic_alloc_pages() functions did not zero out the memory pages they allocate, which may later be available to user-space processes. This flaw could possibly lead to an information leak. (CVE-2009-1192, Low) Bug fixes : * a race in the NFS client between destroying cached access rights and unmounting an NFS file system could have caused a system crash.

    NASL idDEBIAN_DSA-1929.NASL
    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, sensitive memory leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-1883 Solar Designer discovered a missing capability check in the z90crypt driver or s390 systems. This vulnerability may allow a local user to gain elevated privileges. - CVE-2009-2909 Arjan van de Ven discovered an issue in the AX.25 protocol implementation. A specially crafted call to setsockopt() can result in a denial of service (kernel oops). - CVE-2009-3001 Jiri Slaby fixed a sensitive memory leak issue in the ANSI/IEEE 802.2 LLC implementation. This is not exploitable in the Debian lenny kernel as root privileges are required to exploit this issue. - CVE-2009-3002 Eric Dumazet fixed several sensitive memory leaks in the IrDA, X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and Controller Area Network (CAN) implementations. Local users can exploit these issues to gain access to kernel memory. - CVE-2009-3228 Eric Dumazet reported an instance of uninitialized kernel memory in the network packet scheduler. Local users may be able to exploit this issue to read the contents of sensitive kernel memory. - CVE-2009-3238 Linus Torvalds provided a change to the get_random_int() function to increase its randomness. - CVE-2009-3286 Eric Paris discovered an issue with the NFSv4 server implementation. When an O_EXCL create fails, files may be left with corrupted permissions, possibly granting unintentional privileges to other local users. - CVE-2009-3547 Earl Chew discovered a NULL pointer dereference issue in the pipe_rdwr_open function which can be used by local users to gain elevated privileges. - CVE-2009-3612 Jiri Pirko discovered a typo in the initialization of a structure in the netlink subsystem that may allow local users to gain access to sensitive kernel memory. - CVE-2009-3621 Tomoki Sekiyama discovered a deadlock condition in the UNIX domain socket implementation. Local users can exploit this vulnerability to cause a denial of service (system hang).

    NASL idORACLELINUX_ELSA-2009-1106.NASL
    descriptionFrom Red Hat Security Advisory 2009:1106 : Updated kernel packages that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes : * several flaws were found in the way the Linux kernel CIFS implementation handles Unicode strings. CIFS clients convert Unicode strings sent by a server to their local character sets, and then write those strings into memory. If a malicious server sent a long enough string, it could write past the end of the target memory region and corrupt other memory areas, possibly leading to a denial of service or privilege escalation on the client mounting the CIFS share. (CVE-2009-1439, CVE-2009-1633, Important) * the Linux kernel Network File System daemon (nfsd) implementation did not drop the CAP_MKNOD capability when handling requests from local, unprivileged users. This flaw could possibly lead to an information leak or privilege escalation. (CVE-2009-1072, Moderate) * Frank Filz reported the NFSv4 client was missing a file permission check for the execute bit in some situations. This could allow local, unprivileged users to run non-executable files on NFSv4 mounted file systems. (CVE-2009-1630, Moderate) * a missing check was found in the hypervisor_callback() function in the Linux kernel provided by the kernel-xen package. This could cause a denial of service of a 32-bit guest if an application running in that guest accesses a certain memory location in the kernel. (CVE-2009-1758, Moderate) * a flaw was found in the AGPGART driver. The agp_generic_alloc_page() and agp_generic_alloc_pages() functions did not zero out the memory pages they allocate, which may later be available to user-space processes. This flaw could possibly lead to an information leak. (CVE-2009-1192, Low) Bug fixes : * a race in the NFS client between destroying cached access rights and unmounting an NFS file system could have caused a system crash.

    descriptionThis update fixes various bugs and some security issues in the SUSE Linux Enterprise 10 SP 3 kernel. The following security issues were fixed: CVE-2009-3238: The get_random_int function in drivers/char/random.c in the Linux kernel produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the functions tendency to return the same value over and over again for long stretches of time. - The (1) agp_generic_alloc_page and (2) agp_generic_alloc_pages functions in drivers/char/agp/generic.c in the agp subsystem in the Linux kernel do not zero out pages that may later be available to a user-space process, which allows local users to obtain sensitive information by reading these pages. (CVE-2009-1192) - Unsigned check in the ax25 socket handler could allow local attackers to potentially crash the kernel or even execute code. (CVE-2009-2909)

    descriptionThis update fixes a several security issues and various bugs in the SUSE Linux Enterprise 10 SP 2 kernel. The following security issues were fixed: CVE-2009-3547: A race condition during pipe open could be used by local attackers to elevate privileges. - On x86_64 systems a information leak of high register contents (upper 32bit) was fixed. (CVE-2009-2910) - The randomness of the ASLR methods used in the kernel was increased. (CVE-2009-3238) - A information leak from the kernel due to uninitialized memory in AGP handling was fixed. (CVE-2009-1192) - A signed comparison in the ax25 sockopt handler was fixed which could be used to crash the kernel or potentially execute code. (CVE-2009-2909) - The execve function in the Linux kernel did not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit. (CVE-2009-2848) - Fixed various sockethandler getname leaks, which could disclose memory previously used by the kernel or other userland processes to the local attacker. (CVE-2009-3002) - Multiple buffer overflows in the cifs subsystem in the Linux kernel allow remote CIFS servers to cause a denial of service (memory corruption) and possibly have unspecified other impact via (1) a malformed Unicode string, related to Unicode string area alignment in fs/cifs/sess.c; or (2) long Unicode characters, related to fs/cifs/cifssmb.c and the cifs_readdir function in fs/cifs/readdir.c.
