TITLE:
Ubuntu update for dash

SECUNIA ADVISORY ID:
SA34205

VERIFY ADVISORY:
http://secunia.com/advisories/34205/

DESCRIPTION:
Ubuntu has acknowledged a security issue in dash, which can be
exploited by malicious, local users to gain escalated privileges.

The security issue is caused due to dash sourcing the ".profile" file
from the current working directory when being started as login shell,
which can be exploited to execute arbitrary shell commands with the
privileges of another user by e.g. tricking a victim into starting a
dash login shell in a directory containing a malicious ".profile"
file.

SOLUTION:
Apply updated packages.

-- Ubuntu 8.04 LTS --
