  • Ubuntu 10.04 LTS

Summary

Several security issues were fixed in the kernel.

Software description

  • linux - Linux kernel

Details

A flaw was discovered in the Linux kernel's handling of the SCTP handshake. A
remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2014-0101)

An error was discovered in the Linux kernel's DCCP protocol support. A
remote attacked could exploit this flaw to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2014-2523)

Update instructions

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-58-386 2.6.32-58.120
linux-image-2.6.32-58-lpia 2.6.32-58.120
linux-image-2.6.32-58-ia64 2.6.32-58.120
linux-image-2.6.32-58-versatile 2.6.32-58.120
linux-image-2.6.32-58-server 2.6.32-58.120
linux-image-2.6.32-58-powerpc64-smp 2.6.32-58.120
linux-image-2.6.32-58-generic 2.6.32-58.120
linux-image-2.6.32-58-generic-pae 2.6.32-58.120
linux-image-2.6.32-58-powerpc-smp 2.6.32-58.120
linux-image-2.6.32-58-virtual 2.6.32-58.120
linux-image-2.6.32-58-sparc64-smp 2.6.32-58.120
linux-image-2.6.32-58-powerpc 2.6.32-58.120
linux-image-2.6.32-58-preempt 2.6.32-58.120
linux-image-2.6.32-58-sparc64 2.6.32-58.120

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

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

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.
