MUTE P2P File Sharing Host Selection Weakness

SECUNIA ADVISORY ID:
SA18980

VERIFY ADVISORY:
http://secunia.com/advisories/18980/

CRITICAL:
Not critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
MUTE 0.x
http://secunia.com/product/8279/

DESCRIPTION:
Gary Whetstone has reported a weakness in MUTE, which potentially can
be exploited by malicious people to bypass certain security
restrictions.

A design weakness in the MUTE client causes it to select hosts to
connect to based on 10 random hosts that are retrieved from a single
mWebCache. This can potentially be exploited to cause MUTE to connect
to malicious hosts if the mWebCache has been populated with addresses
of malicious hosts.

Successful exploitation discloses the identity of the MUTE client.

The weakness has been reported in 0.4.1. Other versions may also be
affected.

SOLUTION:
The weakness will reportedly be fixed in the next release.

PROVIDED AND/OR DISCOVERED BY:
Gary Whetstone
