TITLE:
Tumbleweed Email Firewall LHA File Parsing Vulnerabilities

SECUNIA ADVISORY ID:
SA21194

VERIFY ADVISORY:
http://secunia.com/advisories/21194/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
MailGate Email Firewall 6.x
http://secunia.com/product/11136/
Tumbleweed Messaging Management System (MMS) 5.x
http://secunia.com/product/3588/

DESCRIPTION:
Ryan Smith has reported three vulnerabilities in Tumbleweed Email
Firewall, which can be exploited by malicious people to compromise a
vulnerable system.

1) A boundary error within the processing of LHA extended-header
filenames can be exploited to cause a stack-based buffer overflow.

2) A boundary error within the processing of LHA extended-header
directory names can be exploited to cause a stack-based buffer
overflow.

3) A boundary error within the processing of files in LHA archives
can be exploited to cause a stack-based buffer overflow via a
specially crafted LHA archive containing files with overly long
filenames.

Successful exploitation of the vulnerabilities allows execution of
arbitrary code when an e-mail with a specially crafted attachment is
processed.

SOLUTION:
According to the researcher, the vendor will not be releasing a
patch. Instead, the vendor has reportedly suggested a workaround
(contact the vendor for more information).
