TITLE:
dsocks "_tor_resolve" Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA21771

VERIFY ADVISORY:
http://secunia.com/advisories/21771/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
dsocks 1.x
http://secunia.com/product/11897/

DESCRIPTION:
Michael Adams has reported a vulnerability in dsocks, which
potentially can be exploited by malicious people to compromise a
user's system.

The vulnerability is due to a boundary error in the "_tor_resolve()"
function in dsocks.c. This can be exploited to cause a stack-based
buffer overflow when resolving an overly long host name (e.g.
supplied by a malicious website when using dsocks with a browser).

Successful exploitation may allow arbitrary code execution.

SOLUTION:
Update to version 1.4.

PROVIDED AND/OR DISCOVERED BY:
Michael Adams
