Several local and remote vulnerabilities have been discovered in the Linux
kernel that may lead to a denial of service or the execution of arbitrary
code. The Common Vulnerabilities and Exposures project identifies the
Thomas Graf reported a typo in the IPV4 protocol handler that could
be used by a local attacker to overrun an array via crafted packets,
potentially resulting in a Denial of Service (system crash).
The DECnet counterpart of this issue was already fixed in DSA-1356.
iDefense reported a potential integer underflow in the cpuset filesystem
which may permit local attackers to gain access to sensitive kernel
memory. This vulnerability is only exploitable if the cpuset filesystem
The PaX Team discovered a potential buffer overflow in the random number
generator which may permit local users to cause a denial of service or
gain additional privileges. This issue is not believed to effect default
Debian installations where only root has sufficient privileges to exploit
A coding error in the CIFS subsystem permits the use of unsigned messages
even if the client has been configured the system to enforce
signing by passing the sec=ntlmv2i mount option. This may allow remote
attackers to spoof CIFS network traffic.
Alan Cox reported an issue in the aacraid driver that allows unprivileged
local users to make ioctl calls which should be restricted to admin
These problems have been fixed in the stable distribution in version
The following matrix lists additional packages that were rebuilt for
compatibility with or to take advantage of this update:
We recommend that you upgrade your kernel package immediately 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.
