TITLE:
UltraISO ISO File Extraction Directory Traversal Vulnerability

SECUNIA ADVISORY ID:
SA19857

VERIFY ADVISORY:
http://secunia.com/advisories/19857/

CRITICAL:
Less critical

IMPACT:
System access

WHERE:
From remote

SOFTWARE:
UltraISO 8.x

DESCRIPTION:
Sowhat has discovered a vulnerability in UltraISO, 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 from an ISO image. 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 7.6.5.1269, and also
reported in version 8.0.0.1392. Prior versions may also be affected.

SOLUTION:
The vulnerability will reportedly be fixed in the next file update.

Do not extract untrusted ISO files.

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

PROVIDED AND/OR DISCOVERED BY:
