TITLE:
Borland VisiBroker Smart Agent Packet Handling Vulnerabilities

SECUNIA ADVISORY ID:
SA29213

VERIFY ADVISORY:
http://secunia.com/advisories/29213/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From local network

SOFTWARE:
Borland VisiBroker 8.x
http://secunia.com/product/17859/

DESCRIPTION:
Luigi Auriemma has reported some vulnerabilities in Borland
VisiBroker, which can be exploited by malicious people to cause a DoS
(Denial of Service) or potentially compromise a vulnerable system.

1) An integer overflow error in Smart Agent (osagent.exe) can be
exploited to cause a heap-based buffer overflow via a specially
crafted packet sent to default port 14000/UDP.

Successful exploitation may allow execution of arbitrary code.

2) An input validation in Smart Agent can be exploited to cause the
process to terminate via a specially crafted packet sent to default
port 14000/UDP.

The vulnerabilities are reported in version 8.00.00.C1.03. Other
versions may also be affected.

SOLUTION:
Restrict network access to the service.

PROVIDED AND/OR DISCOVERED BY:
