Debian Security Advisory DSA-XXXX-1 security@debian.org
http://www.debian.org/security/ Dann Frazier
Aug 16, 2009 http://www.debian.org/security/faq
----------------------------------------------------------------------
Package : linux-2.6.24
Vulnerability : privilege escalation
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2009-2692
A vulnerability has been discovered in the Linux kernel that may lead
to privilege escalation. The Common Vulnerabilities and Exposures project
identifies the following problem:
CVE-2009-2692
Tavis Ormandy and Julien Tinnes discovered an issue with how the
sendpage function is initialized in the proto_ops structure.
Local users can exploit this vulnerability to gain elevated
privileges.
For the stable distribution (etch), these problems have been fixed in
version 2.6.24-6~etchnhalf.8etch3.
We recommend that you upgrade your linux-2.6.24 packages.
Note: Debian 'etch' includes linux kernel packages based upon both the
2.6.18 and 2.6.24 linux releases. All known security issues are
carefully tracked against both packages and both packages will receive
security updates until security support for Debian 'etch'
concludes. However, given the high frequency at which low-severity
security issues are discovered in the kernel and the resource
requirements of doing an update, lower severity 2.6.18 and 2.6.24
updates will typically release in a staggered or "leap-frog" fashion.
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
-------------------------------
Oldstable updates are available for alpha, amd64, arm, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
These changes will probably be included in the oldstable distribution on
its next update.
