7-Zip < 16.00 Multiple Vulnerabilities

high Nessus Plugin ID 91230

Language:

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)

Solution

Upgrade to 7-Zip version 16.00 or later.
