TITLE:
Mailutils Four Vulnerabilities

SECUNIA ADVISORY ID:
SA15442

VERIFY ADVISORY:
http://secunia.com/advisories/15442/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
GNU Mailutils 0.x
http://secunia.com/product/5123/

DESCRIPTION:
infamous41md has reported four vulnerabilities in GNU Mailutils,
which can be exploited to cause a DoS (Denial of Service) or
compromise a vulnerable system.

1) An integer overflow in the "fetch_io()" function in imap4d/fetch.c
when handling partial message requests can be exploited by malicious
users to cause a heap-based buffer overflow.

Successful exploitation allows execution of arbitrary code.

2) An input validation error in the imap4d service during processing
of FETCH commands can be exploited by malicious users to cause the
service to consume a large amount of memory resources via a specially
crafted sequence range.

3) A format string error in the imap4d service when handling command
tags can be exploited by malicious people to execute arbitrary code
via a specially crafted string containing format specifiers.

4) A coding error in the "header_get_field_name()" function in
mailbox/header.c can be exploited to cause a buffer overflow via a
specially crafted email.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities have been reported in versions 0.5 and 0.6. Other
versions may also be affected.

SOLUTION:
The vulnerabilities have been fixed in version 0.6.90.
