TITLE:
HPLIP hpssd Command Injection Vulnerability

SECUNIA ADVISORY ID:
SA27202

VERIFY ADVISORY:
http://secunia.com/advisories/27202/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
HPLIB 2.x
http://secunia.com/product/16077/

DESCRIPTION:
Kees Cook has reported a vulnerability in HPLIB, which can be
exploited by malicious, local users to gain escalated privileges.

The vulnerability is caused due to the hpssd daemon not properly
sanitising certain input before using it to invoke sendmail using the
"popen3()" method. This can be exploited to execute arbitrary commands
with escalated privileges (e.g. "root") by sending specially crafted
requests to the hpssd daemon.

NOTE: Depending upon the configuration of hpssd, this may also be
remotely exploitable.

SOLUTION:
Restrict access to trusted people only.

PROVIDED AND/OR DISCOVERED BY:
Kees Cook, Ubuntu Security Team
