TITLE:
Affix Buffer Overflow and Shell Command Injection Vulnerabilities

SECUNIA ADVISORY ID:
SA15988

VERIFY ADVISORY:
http://secunia.com/advisories/15988/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Affix 2.x
http://secunia.com/product/4965/
Affix 3.x
http://secunia.com/product/5366/

DESCRIPTION:
Kevin Finisterre has reported two vulnerabilities in Affix, which can
be exploited by malicious people to compromise a vulnerable system.

1) A boundary error in the processing of filenames in the btftp
client utility can be exploited to cause a buffer overflow via an
overly long filename (more than 101 bytes) by tricking a user into
browsing a malicious OBEX file share through a wireless Bluetooth
connection.

Successful exploitation allows execution of arbitrary code.

2) An input validation error in the handling of filenames in btobex.c
can be exploited to inject arbitrary shell commands by e.g. uploading
a file with a specially crafted filename on a vulnerable btsrv server
through a wireless Bluetooth connection.

The vulnerabilities have been reported in versions 2.1.2 and 3.2.0.
Prior versions may also be affected.

SOLUTION:
Apply patches.

Affix 2.1.2:

Affix 3.2.0:
