CRITICAL:
Less critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
WinAce 2.x
http://secunia.com/product/4231/

DESCRIPTION:
Hamid Ebadi has discovered a vulnerability in WinACE, which
potentially can be exploited by malicious people to compromise a
user's system.

The vulnerability is caused due to an input validation error when
extracting files compressed with RAR (.rar) or TAR (.tar). This makes
it possible to have files extracted to arbitrary locations outside the
specified directory using the "../" directory traversal sequence.

The vulnerability has been confirmed in version 2.6. Other versions
may also be affected.

SOLUTION:
Do not extract untrusted RAR and TAR files.

To reduce the risk, never extract files as an administrative user.
