TITLE:
Ipswitch IMail Server "SEARCH" Command Multiple Buffer Overflows

SECUNIA ADVISORY ID:
SA26193

VERIFY ADVISORY:
http://secunia.com/advisories/26193/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Ipswitch Collaboration Suite (ICS) 2006
http://secunia.com/product/8652/
Ipswitch IMail Server 2006
http://secunia.com/product/8653/

DESCRIPTION:
Multiple vulnerabilities have been discovered in Ipswitch IMail
Server and Ipswitch Collaboration Suite (ICS), which can be exploited
by malicious users to compromise a vulnerable system.

The vulnerabilities are caused due to multiple boundary errors in the
IMAP service when processing certain "SEARCH" command search keys
("BEFORE", "ON", "SINCE", "SENTBEFORE", "SENTON", "SENTSINCE"). This
can be exploited to cause stack-based buffer overflows via overly
long, quoted or unquoted arguments passed to the command.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities are confirmed in IMail Premium versions 2006.2
and 2006.21. Other versions may also be affected.

SOLUTION:
Grant only trusted users access to the IMAP service.

PROVIDED AND/OR DISCOVERED BY:
Independently discovered by:
* Secunia Research
* ZhenHan Liu, Ph4nt0m Security Team.
