Latest Security Advisories & Notable Vulnerabilities

This vulnerability assigned with CVE-2015-3842, affects the AudioEffect component found in the mediaserver program. Attackers can run arbitrary code on the device when successfully exploited thus compromising its security. However, attackers need to convince users first to install a malicious app that doesn't require any permission.The said vulnerability affects Android versions 2.3 to 5.1.1.

Trend Micro researcher Wish Wu disclosed details about this vulnerability to Google. The said company acknowledged Wu’s research contribution.

Trend Micro researchers discovered this Android vulnerability that can modify MMS/SMS when exploited successfully. This bug came from “MessageStatusReceiver” service found in AndroidManifest.XML file. Attackers may exploit this via a malicious application to launch privilege escalation attack to the Android security model to change received status and date of SMS/MMS.

Other possible attack scenarios would be for attackers to leverage this vulnerability to modify the conversation or even have users send messages to a premium number without their knowledge.

Trend Micro researchers discovered this Android vulnerability assigned with CVE-2015-3839 that could allow attackers to put malicious messages in the messaging app, thus causing it to crash. In addition, attackers can also perform denial-of-service (DoS) attacks on the messaging app only (and not the whole device). As such, users won’t be able to receive and send text messages to their contacts.

Attackers need to trick users into installing a malicious app in order to download the said bug on their devices.

  Risk Rating: Important
  
  This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if an attacker first places a specially crafted dynamic link library (DLL) file in the target user’s current working directory and then convinces the user to open a Remote Desktop Protocol (RDP) file or to launch a program that is designed to load a trusted DLL file but instead loads the attacker’s specially crafted DLL file.



• (MS15-083) Vulnerability in Server Message Block Could Allow Remote Code Execution (3073921)
  Risk Rating: Important
  
  This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if an attacker sends a specially crafted string to SMB server error logging.



• (MS15-084) Vulnerabilities in XML Core Services Could Allow Information Disclosure (3080129)
  Risk Rating: Important
  
  This security update resolves vulnerabilities in Microsoft Windows and Microsoft Office. The vulnerabilities could allow information disclosure by either exposing memory addresses if a user clicks a specially crafted link or by explicitly allowing the use of Secure Sockets Layer (SSL) 2.0.



• (MS15-085) Vulnerability in Mount Manager Could Allow Elevation of Privilege (3082487)
  Risk Rating: Important
  
  This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker inserts a malicious USB device into a target system.



• (MS15-086) Vulnerability in System Center Operations Manager Could Allow Elevation of Privilege (3075158)
  Risk Rating: Important
  
  This security update resolves a vulnerability in Microsoft System Center Operations Manager. The vulnerability could allow elevation of privilege if a user visits an affected website by way of a specially crafted URL.



• (MS15-087) Vulnerability in UDDI Services Could Allow Elevation of Privilege (3082459)
  Risk Rating: Important
  
  This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker engineered a cross-site scripting (XSS) scenario by inserting a malicious script into a webpage search parameter.



• (MS15-088) Unsafe Command Line Parameter Passing Could Allow Information Disclosure (3082458)
  Risk Rating: Important
  
  This security update helps to resolve an information disclosure vulnerability in Microsoft Windows, Internet Explorer, and Microsoft Office. To exploit the vulnerability an attacker would first have to use another vulnerability in Internet Explorer to execute code in the sandboxed process.



• (MS15-089) Vulnerability in WebDAV Could Allow Information Disclosure (3076949)
  Risk Rating: Important
  
  This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow information disclosure if an attacker forces an encrypted Secure Socket Layer (SSL) 2.0 session with a WebDAV server that has SSL 2.0 enabled and uses a man-in-the-middle (MiTM) attack to decrypt portions of the encrypted traffic.



• (MS15-090) Vulnerabilities in Microsoft Windows Could Allow Elevation of Privilege (3060716)
  Risk Rating: Important
  
  This security update resolves vulnerabilities in Microsoft Windows. The vulnerabilities could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application or convinces a user to open a specially crafted file that invokes a vulnerable sandboxed application, allowing an attacker to escape the sandbox.



• (MS15-091) Cumulative Security Update for Microsoft Edge (3084525)
  Risk Rating: Critical
  
  This security update resolves vulnerabilities in Microsoft Edge. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Microsoft Edge.



• (MS15-092) Vulnerabilities in .NET Framework Could Allow Elevation of Privilege (3086251)
  Risk Rating: Important
  
  This security update resolves vulnerabilities in Microsoft .NET Framework. The vulnerabilities could allow elevation of privilege if a user runs a specially crafted .NET application.

Trend Micro researchers discovered this vulnerability in Android devices that could potentially allow attackers to perform Denial of Service (DoS) attacks once successfully exploited. It affects Android versions <4.0.1 Jelly Bean to 5.1.1 Lollipop.

Attackers need to trick users into installing a malicious app or go to a malicious website in order to download the said bug on their devices.

This Android vulnerability known as “Stagefright” can be leveraged by attackers to install a malware on Android devices via a multimedia message (MMS). It affects versions of Android from 4.0.1 to 5.1.1. The said vulnerability, designated with CVE-2015-3824, resides in mediaserver component, which is for handling open media files.

This flaw allows remote attackers to read or write to memory thus allowing the execution of arbitrary code via crafted JavaScript. As such, it compromises the security of the system.
