This advisory covers the S/390 components of the recent security update for the Linux 2.6.8 kernel that was missing due to technical problems. For reference below please see the original advisory text.
Several security related problems have been discovered in the Linux kernel which may lead to a denial of service or even the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems:
CVE-2004-2660
Toshihiro Iwamoto discovered a memory leak in the handling of direct I/O writes that allows local users to cause a denial of service.
CVE-2005-4798
A buffer overflow in NFS readlink handling allows a malicious remote server to cause a denial of service.
CVE-2006-1052
Stephen Smalley discovered a bug in the SELinux ptrace handling that allows local users with ptrace permissions to change the tracer SID to the SID of another process.
CVE-2006-1343
Pavel Kankovsky discovered an information leak in the getsockopt system call which can be exploited by a local program to leak potentially sensitive memory to userspace.
CVE-2006-1528
Douglas Gilbert reported a bug in the sg driver that allows local users to cause a denial of service by performing direct I/O transfers from the sg driver to memory mapped I/O space.
CVE-2006-1855
Mattia Belletti noticed that certain debugging code left in the process management code could be exploited by a local attacker to cause a denial of service.
CVE-2006-1856
Kostik Belousov discovered a missing LSM file_permission check in the readv and writev functions which might allow attackers to bypass intended access restrictions.
CVE-2006-2444
Patrick McHardy discovered a bug in the SNMP NAT helper that allows remote attackers to cause a denial of service.
CVE-2006-2446
A race condition in the socket buffer handling allows remote attackers to cause a denial of service.
CVE-2006-2935
Diego Calleja Garcia discovered a buffer overflow in the DVD handling code that could be exploited by a specially crafted DVD or USB storage device to execute arbitrary code.
CVE-2006-2936
A bug in the serial USB driver has been discovered that could be exploited by a custom made USB serial adapter to consume arbitrary amounts of memory.
CVE-2006-3468
James McKenzie discovered a denial of service vulnerability in the NFS driver. When exporting an ext3 file system over NFS, a remote attacker could exploit this to trigger a file system panic by sending a specially crafted UDP packet.
CVE-2006-3745
Wei Wang discovered a bug in the SCTP implementation that allows local users to cause a denial of service and possibly gain root privileges.
CVE-2006-4093
Olof Johansson discovered that the kernel did not disable the HID0 bit on PowerPC 970 processors which could be exploited by a local attacker to cause a denial of service.
CVE-2006-4145
A bug in the Universal Disk Format (UDF) filesystem driver could be exploited by a local user to cause a denial of service.
CVE-2006-4535
David Miller reported a problem with the fix for CVE-2006-3745 that allows local users to crash the system using via an SCTP socket with a certain SO_LINGER value.
The following matrix explains which kernel version for which architecture fixes the problem mentioned above:
stable (sarge) Source 2.6.8-16sarge5 Alpha architecture 2.6.8-16sarge5 AMD64 architecture 2.6.8-16sarge5 HP Precision architecture 2.6.8-6sarge5 Intel IA-32 architecture 2.6.8-16sarge5 Intel IA-64 architecture 2.6.8-14sarge5 Motorola 680x0 architecture 2.6.8-4sarge5 PowerPC architecture 2.6.8-12sarge5 IBM S/390 2.6.8-5sarge5 Sun Sparc architecture 2.6.8-15sarge5 FAI 1.9.1sarge4
Due to some internal problems kernel packages for the S/390 are missing and will be provided later.
For the unstable distribution (sid) these problems have been fixed in version 2.6.18-1.
We recommend that you upgrade your kernel package and reboot the machine. If you have built a custom kernel from the kernel source package, you will need to rebuild to take advantage of these fixes.
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 at the end of this advisory:
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.
