Launched less than a year ago, the No More Ransom (NMR) project has increased its capacity with new partners and new decryption tools added to its now global campaign to combat Ransomware.
Started as a joint initiative by Europol, the Dutch National Police, Intel Security and Kaspersky Lab, No More Ransom is an anti-ransomware cross-industry
At the Kaspersky Lab Security Analyst Summit, one researcher shared how he was able to find corporate emails, confidential business plans and classified FBI flash alerts.
Multiple Access Control issues in Trend Micro InterScan Web Security Virtual Appliance (IWSVA) 6.5 before CP 1746 allow an authenticated, remote user with low privileges like ‘Reports Only’ or ‘Auditor’ to change FTP Access Control Settings, create or modify reports, or upload an HTTPS Decryption Certificate and Private Key.
Trend Micro InterScan Web Security Virtual Appliance (IWSVA) 6.5 before CP 1746 mismanages certain key and certificate data. Per IWSVA documentation, by default, IWSVA acts as a private Certificate Authority (CA) and dynamically generates digital certificates that are sent to client browsers to complete a secure passage for HTTPS connections. It also allows administrators to upload their own certificates signed by a root CA. An attacker with low privileges can download the current CA certificate and Private Key (either the default ones or ones uploaded by administrators) and use those to decrypt HTTPS traffic, thus compromising confidentiality. Also, the default Private Key on this appliance is encrypted with a very weak passphrase. If an appliance uses the default Certificate and Private Key provided by Trend Micro, an attacker can simply download these and decrypt the Private Key using the default/weak passphrase.
Trend Micro InterScan Web Security Virtual Appliance (IWSVA) 6.5 before CP 1746 does not sanitize a rest/commonlog/report/template name field, which allows a ‘Reports Only’ user to inject malicious JavaScript while creating a new report. Additionally, IWSVA implements incorrect access control that allows any authenticated, remote user (even with low privileges like ‘Auditor’) to create or modify reports, and consequently take advantage of this XSS vulnerability. The JavaScript is executed when victims visit reports or auditlog pages.
Red Hat Security Advisory 2017-0881-01 – V8 is Google’s open source JavaScript engine. V8 is written in C++ and is used in Google Chrome, the open source browser from Google. V8 implements ECMAScript as specified in ECMA-262, 3rd edition. Security Fix: An integer-overflow flaw was found in V8’s Zone class when allocating new memory and Zone::NewExpand()). An attacker with the ability to manipulate a large zone could crash the application or, potentially, execute arbitrary code with the application privileges.

Ubuntu Security Notice 3256-1 – Andrey Konovalov discovered that the AF_PACKET implementation in the Linux kernel did not properly validate certain block-size data. A local attacker could use this to cause a denial of service.
Ubuntu Security Notice 3256-2 – USN-3256-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, and Ubuntu 16.10. This update provides the corresponding updates for the Linux Hardware Enablement kernel for each of the respective prior Ubuntu LTS releases. Andrey Konovalov discovered that the AF_PACKET implementation in the Linux kernel did not properly validate certain block-size data. A local attacker could use this to cause a denial of service. Various other issues were also addressed.
