TITLE:
IMail IMAP Service DELETE Command Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA13200

VERIFY ADVISORY:
http://secunia.com/advisories/13200/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
From remote

SOFTWARE:
IMail Server 8.x
http://secunia.com/product/3048/

DESCRIPTION:
Muts has discovered a vulnerability in IMail Server, which can be
exploited by malicious users to compromise a vulnerable system.

The vulnerability is caused due to a boundary error within the IMAP
service ("IMAP4D32.exe") when processing "DELETE" commands. This can
be exploited to cause a stack-based buffer overflow by passing a
"DELETE" command with an overly long argument (about 300 bytes).

Successful exploitation allows execution of arbitrary code.

The vulnerability has been confirmed in version 8.13. Other versions
may also be affected.

SOLUTION:
Restrict access to the IMAP service or disable it.

PROVIDED AND/OR DISCOVERED BY:
Muts
