7-Zip < 16.00 Multiple Vulnerabilities

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

A compression utility installed on the remote Windows host is affected
by multiple vulnerabilities.

Description :

The version of 7-Zip installed on the remote Windows host is prior to
16.0. It is, therefore, affected by multiple vulnerabilities :

- A heap buffer overflow condition exits in the
CHandler::ExtractZlibFile() function within file
Archive\HfsHandler.cpp due to improper validation of
user-supplied input. An unauthenticated, remote attacker
can exploit this by convincing a user to open a
specially crafted file, resulting in the execution of
arbitrary code. (CVE-2016-2334)

- An out-of-bounds read error exists in the
CInArchive::ReadFileItem() function within file
Archive\Udf\UdfIn.cpp when handling Universal Disk
Format (UDF) files. An unauthenticated, remote attacker
can exploit this by convincing a user to open a
specially crafted UDF file, resulting in the execution
of arbitrary code. (CVE-2016-2335)
