Security Update: Debian Linux Kernel Local / Remote Vulnerabilities

Debian project today released a pair of security updates to plug at least ten security holes in its core called Linux kernel. Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. This update has been rated as having important security impact.

For the stable distribution (etch), these problems have been fixed in version 2.6.24-6~etchnhalf.7. This is not just Debian specific bug. Other distros will also provide updates.

Problem Description

CVE-2008-3528
    Eugene Teo reported a local DoS issue in the ext2 and ext3
    filesystems.  Local users who have been granted the privileges
    necessary to mount a filesystem would be able to craft a corrupted
    filesystem that causes the kernel to output error messages in an
    infinite loop.
CVE-2008-4554
    Milos Szeredi reported that the usage of splice() on files opened
    with O_APPEND allows users to write to the file at arbitrary
    offsets, enabling a bypass of possible assumed semantics of the
    O_APPEND flag.
CVE-2008-4576
    Vlad Yasevich reported an issue in the SCTP subsystem that may
    allow remote users to cause a local DoS by triggering a kernel
    oops.
CVE-2008-4618
    Wei Yongjun reported an issue in the SCTP subsystem that may allow
    remote users to cause a local DoS by triggering a kernel panic.
CVE-2008-4933
    Eric Sesterhenn reported a local DoS issue in the hfsplus
    filesystem.  Local users who have been granted the privileges
    necessary to mount a filesystem would be able to craft a corrupted
    filesystem that causes the kernel to overrun a buffer, resulting
    in a system oops or memory corruption.
CVE-2008-4934
    Eric Sesterhenn reported a local DoS issue in the hfsplus
    filesystem.  Local users who have been granted the privileges
    necessary to mount a filesystem would be able to craft a corrupted
    filesystem that results in a kernel oops due to an unchecked
    return value.
CVE-2008-5025
    Eric Sesterhenn reported a local DoS issue in the hfs filesystem.
    Local users who have been granted the privileges necessary to
    mount a filesystem would be able to craft a filesystem with a
    corrupted catalog name length, resulting in a system oops or
    memory corruption.
CVE-2008-5029
    Andrea Bittau reported a DoS issue in the unix socket subsystem
    that allows a local user to cause memory corruption, resulting in
    a kernel panic.
CVE-2008-5134
    Johannes Berg reported a remote DoS issue in the libertas wireless
    driver, which can be triggered by a specially crafted beacon/probe
    response.
CVE-2008-5182
    Al Viro reported race conditions in the inotify subsystem that may
    allow local users to acquire elevated privileges.
CVE-2008-5300
    Dann Frazier reported a DoS condition that allows local users to
    cause the out of memory handler to kill off privileged processes
    or trigger soft lockups due to a starvation issue in the unix
    socket subsystem.
