TITLE:
Ipswitch Collaboration Suite IMAP EXAMINE Buffer Overflow

SECUNIA ADVISORY ID:
SA14546

VERIFY ADVISORY:
http://secunia.com/advisories/14546/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Ipswitch Collaboration Suite (ICS) 1.x
http://secunia.com/product/4773/
IMail Server 8.x
http://secunia.com/product/3048/

DESCRIPTION:
Nico Steinhardt has reported a vulnerability in Ipswitch
Collaboration Suite, which can be exploited by malicious users to
compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the IMAP4
service (IMAP4d32.exe) shipped with IMail Server, which is now part
of Ipswitch Collaboration Suite. This can be exploited to cause a
buffer overflow by passing an overly long string (about 259 bytes) as
argument to the "EXAMINE" command.

Successful exploitation allows execution of arbitrary code.

The vulnerability has been reported in IMAP4d32.exe version
12.8.27.14 (included in IMail Server 8.13). Other versions may also
be affected.

SOLUTION:
Apply IMail Server 8.15 Hotfix 1:
ftp://ftp.ipswitch.com/Ipswitch/Product_Support/IMail/IM815HF1.exe

PROVIDED AND/OR DISCOVERED BY:
