TITLE:
SAP GUI SAPLPD Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA28786

VERIFY ADVISORY:
http://secunia.com/advisories/28786/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From local network

SOFTWARE:
SAP GUI 7.x
http://secunia.com/product/16959/

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

1) Multiple boundary errors exist in the SAPLPD server when
processing LPD commands. This can be exploited to cause buffer
overflows via overly long arguments passed to the LPD commands having
the following codes: 0x01, 0x02, 0x03, 0x04, 0x05, 0x31, 0x32, 0x33,
0x34, and 0x35.

Successful exploitation may allow execution of arbitrary code.

2) An error in SAPLPD when processing the 0x53 LPD command code can
be exploited to terminate an affected server.

The vulnerabilities are confirmed in SAPLPD version 6.28.0.1 included
in SAP GUI version 7.10. Other versions may also be affected.

SOLUTION:
Restrict access to TCP port 515. The vendor will reportedly release a
patch soon.
