TITLE:
Debian toolchain-source "tpkg-*" Privilege Escalation

SECUNIA ADVISORY ID:
SA14277

VERIFY ADVISORY:
http://secunia.com/advisories/14277/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
Debian GNU/Linux 3.0
http://secunia.com/product/143/
Debian GNU/Linux unstable alias sid
http://secunia.com/product/530/

DESCRIPTION:
Sean Finney has reported some vulnerabilities in toolchain-source,
which can be exploited by malicious, local users to perform certain
actions on a vulnerable system with escalated privileges.

The vulnerabilities are caused due to temporary files being created
insecurely. This can be exploited via symlink attacks to overwrite
arbitrary files with the privileges of the user running the "tpkg-*"
scripts.

SOLUTION:
Apply updated packages.
