===========================================================
Ubuntu Security Notice USN-732-1             March 10, 2009
dash vulnerability
CVE-2009-0854
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 8.04 LTS
Ubuntu 8.10

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 8.04 LTS:
  dash                            0.5.4-8ubuntu1.1

Ubuntu 8.10:
  dash                            0.5.4-9ubuntu1.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

Wolfgang M. Reimer discovered that dash, when invoked as a login shell, would
source .profile files from the current directory. Local users may be able to
bypass security restrictions and gain root privileges by placing specially
crafted .profile files where they might get sourced by other dash users.
