Package : linux-2.6.24
Vulnerability : denial of service/privilege escalation
Problem type : local/remote
Debian-specific: no
CVE Id(s) : CVE-2008-3528 CVE-2008-4554 CVE-2008-4576 CVE-2008-4618
CVE-2008-4933 CVE-2008-4934 CVE-2008-5025 CVE-2008-5029
CVE-2008-5134 CVE-2008-5182 CVE-2008-5300

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

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.

For the stable distribution (etch), these problems have been fixed in
version 2.6.24-6~etchnhalf.7.

We recommend that you upgrade your linux-2.6.24 packages.

Upgrade instructions
- --------------------

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

Debian GNU/Linux 4.0 alias etch
