Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2004-2731     infamous41md reported multiple integer overflows in the     Sbus PROM driver that would allow for a DoS (Denial of     Service) attack by a local user, and possibly the     execution of arbitrary code.

  - CVE-2006-4814     Doug Chapman discovered a potential local DoS (deadlock)     in the mincore function caused by improper lock     handling.

  - CVE-2006-5753     Eric Sandeen provided a fix for a local memory     corruption vulnerability resulting from a     misinterpretation of return values when operating on     inodes which have been marked bad.

  - CVE-2006-5823     LMH reported a potential local DoS which could be     exploited by a malicious user with the privileges to     mount and read a corrupted cramfs filesystem.

  - CVE-2006-6053     LMH reported a potential local DoS which could be     exploited by a malicious user with the privileges to     mount and read a corrupted ext3 filesystem.

  - CVE-2006-6054     LMH reported a potential local DoS which could be     exploited by a malicious user with the privileges to     mount and read a corrupted ext2 filesystem.

  - CVE-2006-6106     Marcel Holtman discovered multiple buffer overflows in     the Bluetooth subsystem which can be used to trigger a     remote DoS (crash) and potentially execute arbitrary     code.

  - CVE-2007-1353     Ilja van Sprundel discovered that kernel memory could be     leaked via the Bluetooth setsockopt call due to an     uninitialized stack buffer. This could be used by local     attackers to read the contents of sensitive kernel     memory.

  - CVE-2007-1592     Masayuki Nakagawa discovered that flow labels were     inadvertently being shared between listening sockets and     child sockets. This defect can be exploited by local     users to cause a DoS (Oops).

  - CVE-2007-2172     Thomas Graf reported a typo in the DECnet protocol     handler that could be used by a local attacker to     overrun an array via crafted packets, potentially     resulting in a Denial of Service (system crash). A     similar issue exists in the IPV4 protocol handler and     will be fixed in a subsequent update.

  - CVE-2007-2525     Florian Zumbiehl discovered a memory leak in the PPPOE     subsystem caused by releasing a socket before     PPPIOCGCHAN is called upon it. This could be used by a     local user to DoS a system by consuming all available     memory.

  - CVE-2007-3848     Wojciech Purczynski discovered that pdeath_signal was     not being reset properly under certain conditions which     may allow local users to gain privileges by sending     arbitrary signals to suid binaries.

  - CVE-2007-4308     Alan Cox reported an issue in the aacraid driver that     allows unprivileged local users to make ioctl calls     which should be restricted to admin privileges.

  - CVE-2007-4311     PaX team discovered an issue in the random driver where     a defect in the reseeding code leads to a reduction in     entropy.

  - CVE-2007-5093     Alex Smith discovered an issue with the pwc driver for     certain webcam devices. If the device is removed while a     userspace application has it open, the driver will wait     for userspace to close the device, resulting in a     blocked USB subsystem. This issue is of low security     impact as it requires the attacker to either have     physical access to the system or to convince a user with     local access to remove the device on their behalf.

  - CVE-2007-6063     Venustech AD-LAB discovered a a buffer overflow in the     isdn ioctl handling, exploitable by a local user.

  - CVE-2007-6151     ADLAB discovered a possible memory overrun in the ISDN     subsystem that may permit a local user to overwrite     kernel memory by issuing ioctls with unterminated data.

  - CVE-2007-6206     Blake Frantz discovered that when a core file owned by a     non-root user exists, and a root-owned process dumps     core over it, the core file retains its original     ownership. This could be used by a local user to gain     access to sensitive information.

  - CVE-2007-6694     Cyrill Gorcunov reported a NULL pointer dereference in     code specific to the CHRP PowerPC platforms. Local users     could exploit this issue to achieve a Denial of Service     (DoS).

  - CVE-2008-0007     Nick Piggin of SuSE discovered a number of issues in     subsystems which register a fault handler for memory     mapped areas. This issue can be exploited by local users     to achieve a Denial of Service (DoS) and possibly     execute arbitrary code.

The following matrix lists additional packages that were rebuilt for compatibility with or to take advantage of this update :

Philipp Richter discovered that the AppleTalk protocol handler did not sufficiently verify the length of packets. By sending a crafted AppleTalk packet, a remote attacker could exploit this to crash the kernel. (CVE-2007-1357)

Gabriel Campana discovered that the do_ipv6_setsockopt() function did not sufficiently verifiy option values for IPV6_RTHDR. A local attacker could exploit this to trigger a kernel crash. (CVE-2007-1388)

A Denial of Service vulnerability was discovered in the nfnetlink_log() netfilter function. A remote attacker could exploit this to trigger a kernel crash. (CVE-2007-1496)

The connection tracking module for IPv6 did not properly handle the status field when reassembling fragmented packets, so that the final packet always had the 'established' state. A remote attacker could exploit this to bypass intended firewall rules. (CVE-2007-1497)

Masayuki Nakagawa discovered an error in the flowlabel handling of IPv6 network sockets. A local attacker could exploit this to crash the kernel. (CVE-2007-1592)

The do_dccp_getsockopt() function did not sufficiently verify the optlen argument. A local attacker could exploit this to read kernel memory (which might expose sensitive data) or cause a kernel crash.
This only affects Ubuntu 7.04. (CVE-2007-1730)

The IPv4 and DECnet network protocol handlers incorrectly declared an array variable so that it became smaller than intended. By sending crafted packets over a netlink socket, a local attacker could exploit this to crash the kernel. (CVE-2007-2172).

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 fixes the following security problems :

  - CVE-2007-1000 A NULL pointer dereference in the IPv6     sockopt handling can be used by local attackers to read     arbitrary kernel memory and so gain access to private     information.

  - CVE-2007-1388 A NULL pointer dereference could be used     by local attackers to cause a Oops / crash of the     machine.

  - CVE-2007-1592 A possible double free in the     ipv6/flowlabel handling was fixed.

  - CVE-2007-1357 A remote denial of service attack in the     AppleTalk protocol handler was fixed. This attack is     only possible on the local subnet, and requires the     AppleTalk protocol module to be loaded (which is not     done by default).

Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel :

When SELinux hooks are enabled, the kernel could allow a local user to cause a DoS (crash) via a malformed file stream that triggers a NULL pointer derefernece (CVE-2006-6056).

Multiple buffer overflows in the (1) read and (2) write handlers in the Omnikey CardMan 4040 driver in the Linux kernel before 2.6.21-rc3 allow local users to gain privileges. (CVE-2007-0005)

The Linux kernel version 2.6.13 to 2.6.20.1 allowed a remote attacker to cause a DoS (oops) via a crafted NFSACL2 ACCESS request that triggered a free of an incorrect pointer (CVE-2007-0772).

A local user could read unreadable binaries by using the interpreter (PT_INTERP) functionality and triggering a core dump; a variant of CVE-2004-1073 (CVE-2007-0958).

The ipv6_getsockopt_sticky function in net/ipv6/ipv6_sockglue.c in the Linux kernel before 2.6.20.2 allows local users to read arbitrary kernel memory via certain getsockopt calls that trigger a NULL dereference. (CVE-2007-1000)

Buffer overflow in the bufprint function in capiutil.c in libcapi, as used in Linux kernel 2.6.9 to 2.6.20 and isdn4k-utils, allows local users to cause a denial of service (crash) and possibly gain privileges via a crafted CAPI packet. (CVE-2007-1217)

The do_ipv6_setsockopt function in net/ipv6/ipv6_sockglue.c in Linux kernel 2.6.17, and possibly other versions, allows local users to cause a denial of service (oops) by calling setsockopt with the IPV6_RTHDR option name and possibly a zero option length or invalid option value, which triggers a NULL pointer dereference.
(CVE-2007-1388)

net/ipv6/tcp_ipv6.c in Linux kernel 2.4 and 2.6.x up to 2.6.21-rc3 inadvertently copies the ipv6_fl_socklist from a listening TCP socket to child sockets, which allows local users to cause a denial of service (OOPS) or double-free by opening a listeing IPv6 socket, attaching a flow label, and connecting to that socket. (CVE-2007-1592)
