Packages

Details

Matthew Daley reported an information leak in the floppy disk driver of the
Linux kernel. An unprivileged local user could exploit this flaw to obtain
potentially sensitive information from kernel memory. (CVE-2014-1738)

Matthew Daley reported a flaw in the handling of ioctl commands by the
floppy disk driver in the Linux kernel. An unprivileged local user could
exploit this flaw to gain administrative privileges if the floppy disk
module is loaded. (CVE-2014-1737)

A flaw was discovered in the Reliable Datagram Sockets (RDS) protocol
implementation in the Linux kernel for systems that lack RDS transports. An
unprivileged local user could exploit this flaw to cause a denial of
service (system crash). (CVE-2013-7339)

denial of service (system crash) or possibly have unspecified other impact.

Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.

The problem can be corrected by updating your system to the following package versions:

Ubuntu Release Package Version
10.04 lucid linux-image-2.6.32-364-ec2 –  2.6.32-364.77
