USN-1489-1: Linux kernel (Oneiric backport) vulnerability
29 June 2012
The system could be made to crash if it received specially crafted network traffic.
Releases
Packages
- linux-lts-backport-oneiric - Linux kernel backport from Oneiric
Details
A flaw was discovered in the Linux kernel's NFSv4 (Network file system)
handling of ACLs (access control lists). A remote NFS server (attacker)
could cause a denial of service (OOPS).
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 10.04
-
linux-image-3.0.0-22-virtual
-
3.0.0-22.36~lucid1
-
linux-image-3.0.0-22-generic-pae
-
3.0.0-22.36~lucid1
-
linux-image-3.0.0-22-server
-
3.0.0-22.36~lucid1
-
linux-image-3.0.0-22-generic
-
3.0.0-22.36~lucid1
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.
