SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/19296/

CRITICAL:
Less critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
WinHKI 1.x
http://secunia.com/product/4486/

DESCRIPTION:
Hamid Ebadi has discovered a vulnerability in WinHKI, 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) or ZIP
(.zip) or TAR.GZ (tar.gz). 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 1.6. Other versions
may also be affected.

SOLUTION:
Do not extract untrusted RAR, TAR, ZIP, and TAR.GZ files.

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