TITLE:
Debian update for module-assistant

SECUNIA ADVISORY ID:
SA17267

VERIFY ADVISORY:
http://secunia.com/advisories/17267/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
Debian GNU/Linux 3.1
http://secunia.com/product/5307/
Debian GNU/Linux unstable alias sid
http://secunia.com/product/530/

DESCRIPTION:
Debian has issued an update for module-assistant. This fixes a
vulnerability, which potentially can be exploited by malicious, local
users to perform certain actions on a vulnerable system with escalated
privileges.

The vulnerability is caused due to an insecure temporary file
creation error in the module-assistant rule-file. This can
potentially be exploited via symlink attacks to create or overwrite
arbitrary files with the privileges of the user running the affected
script.

SOLUTION:
Apply updated packages.
