[guru] MailEnable IMAP es POP szerviz javitasok
DATE: Fri, 22 Dec 2006 11:20:19 +0100
Több hibát találtak a MailEnable Microsoft Windows alapú levelző
szerver IMAP és POP szervízeiben.
* Buffer overflow az IMAP szervíz (MEIMAPS.exe) EXAMINE és SELECT
parancsok argumentumkezelésében; a hiba kihasználásával tetszőleges
kód futtatható.
* Input ellenőrzési hiba az IMAP szervíz DELETE parancs
argumentumkezelésében, mellyel a szervíz crash-elhető.
* Stack-based buffer overflow érhető el speciális paraméterezésű parancs
küldésével `Not Authenticated' állapotban az IMAP szervízben, mellyel
tetszőleges kód futtatható.
* Buffer overflow a POP szervíz PASS parancs argumentumkezelésében,
mellyel szintén kód futtatható.
Kiadták a javításokat.

4) Description of Vulnerability
Secunia Research has discovered two vulnerabilities in MailEnable,
which can be exploited by malicious users to cause a DoS (Denial of
service) or compromise a vulnerable system.
1) A boundary error in the handling of arguments passed to the EXAMINE
and SELECT commands within the IMAP service (MEIMAPS.EXE) can be
exploited to cause a stack-based buffer overflow via an overly long
argument.
Successful exploitation allows execution of arbitrary code.
2) An input validation error in the handling of arguments passed to
the DELETE command within the IMAP service (MEIMAPS.EXE) can be
exploited to cause a stack overflow and crash the service by sending
an overly long argument consisting of "*" or "?" characters.
======================================================================

4) Description of Vulnerability
Secunia Research has discovered a vulnerability in MailEnable, which
can be exploited by malicious people to compromise a vulnerable
system.
The vulnerability is caused due to a boundary error when processing
data sent to the IMAP server. This can be exploited to cause a
stack-based buffer overflow by first sending a command in the "Not
Authenticated" state (e.g. "login" command) with a specially crafted
parameter to make the IMAP service wait for more incoming data and
then sending an overly long string (greater than 512 bytes).
Successful exploitation allows execution of arbitrary code.
