Updated kernel packages that fix several security issues and bugs in the Red Hat Enterprise Linux 4 kernel are now available.

This security advisory has been rated as having moderate security impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the security issues described below :

* a flaw in the ISDN CAPI subsystem that allowed a remote user to cause a denial of service or potential remote access. Exploitation would require the attacker to be able to send arbitrary frames over the ISDN network to the victim's machine. (CVE-2007-1217, Moderate)

* a flaw in the perfmon subsystem on ia64 platforms that allowed a local user to cause a denial of service. (CVE-2006-0558, Moderate)

In addition, the following bugs were addressed :

* a panic after reloading of the LSI Fusion driver.

* a vm performance problem was corrected by balancing inactive page lists.

* added a nodirplus option to address NFSv3 performance issues with large directories.

* changed the personality handling to disallow personality changes of setuid and setgid binaries. This ensures they keep any randomization and Exec-shield protection.

All Red Hat Enterprise Linux 4 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.

Updated kernel packages that fix various security issues in the Red Hat Enterprise Linux 5 kernel are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the following security issues :

* a flaw in the DRM driver for Intel graphics cards that allowed a local user to access any part of the main memory. To access the DRM functionality a user must have access to the X server which is granted through the graphical login. This also only affected systems with an Intel 965 or later graphic chipset. (CVE-2007-3851, Important)

* a flaw in the VFAT compat ioctl handling on 64-bit systems that allowed a local user to corrupt a kernel_dirent struct and cause a denial of service (system crash). (CVE-2007-2878, Important)

* a flaw in the connection tracking support for SCTP that allowed a remote user to cause a denial of service by dereferencing a NULL pointer. (CVE-2007-2876, Important)

* flaw in the CIFS filesystem which could cause the umask values of a process to not be honored. This affected CIFS filesystems where the Unix extensions are supported. (CVE-2007-3740, Important)

* a flaw in the stack expansion when using the hugetlb kernel on PowerPC systems that allowed a local user to cause a denial of service. (CVE-2007-3739, Moderate)

* a flaw in the ISDN CAPI subsystem that allowed a remote user to cause a denial of service or potential remote access. Exploitation would require the attacker to be able to send arbitrary frames over the ISDN network to the victim's machine. (CVE-2007-1217, Moderate)

* a flaw in the cpuset support that allowed a local user to obtain sensitive information from kernel memory. To exploit this the cpuset filesystem would have to already be mounted. (CVE-2007-2875, Moderate)

* a flaw in the CIFS handling of the mount option 'sec=' that didn't enable integrity checking and didn't produce any error message.
(CVE-2007-3843, Low)

Red Hat Enterprise Linux 5 users are advised to upgrade to these packages, which contain backported patches to correct these issues.

* various flaws in the supported filesystems that allowed a local privileged user to cause a denial of service. (CVE-2006-6054, CVE-2006-6058, Low)

Red Hat would like to thank Ilja van Sprundel for reporting an issue fixed in this erratum.

All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels to these updated packages, which contain backported fixes to correct these issues.

The remote host is affected by the vulnerability described in GLSA-200704-23 (capi4k-utils: Buffer overflow)

    The bufprint() function in capi4k-utils fails to properly check     boundaries of data coming from CAPI packets.
  Impact :

    A local attacker could possibly escalate privileges or cause a Denial     of Service by sending a crafted CAPI packet.
  Workaround :

    There is no known workaround at this time.

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)

The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels immediately and reboot to effect the fixes.

In addition to these security fixes, other fixes have been included such as :

  - Suspend to disk speed improvements

    - Add nmi watchdog support for core2

    - Add atl1 driver
