TITLE:
Symark PowerBroker Client Binaries Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA29111

VERIFY ADVISORY:
http://secunia.com/advisories/29111/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Symark PowerBroker
http://secunia.com/product/17834/

DESCRIPTION:
Michael Ligh and Greg Sinclair have reported some vulnerabilities in
Symark PowerBroker, which can be exploited by malicious, local users
to gain escalated privileges.

The vulnerabilities are caused due to boundary errors within the
pbrun, pbsh, and pbksh SUID binaries. These can be exploited to cause
stack-based buffer overflows by executing the vulnerable binaries with
an overly long "argv[0]" string.

The vulnerabilities are reported in versions 2.8 through 5.0.1.

SOLUTION:
Apply vendor service packs (see vendor advisory for details).

PROVIDED AND/OR DISCOVERED BY:
Michael Ligh of MNIN.org and Greg Sinclair of NNL-Labs.
