===========================================================
Ubuntu Security Notice USN-1098-1            March 29, 2011
vsftpd vulnerability
CVE-2011-0762
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 8.04 LTS
Ubuntu 9.10
Ubuntu 10.04 LTS
Ubuntu 10.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 6.06 LTS:
  vsftpd                          2.0.4-0ubuntu4.1

Ubuntu 8.04 LTS:
  vsftpd                          2.0.6-1ubuntu1.2

Ubuntu 9.10:
  vsftpd                          2.2.0-1ubuntu2.1

Ubuntu 10.04 LTS:
  vsftpd                          2.2.2-3ubuntu6.1

Ubuntu 10.10:
  vsftpd                          2.3.0~pre2-4ubuntu2.2

In general, a standard system update will make all the necessary changes.

Details follow:

It was discovered that vsftpd incorrectly handled certain glob expressions.
A remote authenticated user could use a crafted glob expression to cause
vftpd to consume all resources, leading to a denial of service.
