Microsoft's Final 2023 Patch Tuesday: 34 Flaws Fixed, Including 4 Critical

Microsoft's Final 2023 Patch Tuesday: 34 Flaws Fixed, Including 4 Critical

Dec 13, 2023 Patch Tuesday / Windows Security
Microsoft released its final set of Patch Tuesday updates for 2023, closing out 34 flaws in its software, making it one of the lightest releases in recent years. Of the 34 shortcomings, four are rated Critical and 30 are rated Important in severity. The fixes are in addition to  18 flaws  Microsoft addressed in its Chromium-based Edge browser since the release of  Patch Tuesday updates for November 2023 . According to data from the  Zero Day Initiative , the software giant has patched more than 900 flaws this year, making it one of the busiest years for Microsoft patches. For comparison, Redmond resolved 917 CVEs in 2022. While none of the vulnerabilities are listed as publicly known or under active attack at the time of release, some of the notable ones are listed below - CVE-2023-35628  (CVSS score: 8.1) - Windows MSHTML Platform Remote Code Execution Vulnerability CVE-2023-35630  (CVSS score: 8.8) - Internet Connection Sharing (ICS) Remote Code Execution Vulnerability CVE-2
Reptar: New Intel CPU Vulnerability Impacts Multi-Tenant Virtualized Environments

Reptar: New Intel CPU Vulnerability Impacts Multi-Tenant Virtualized Environments

Nov 15, 2023 Vulnerability / Hardware Security
Intel has released fixes to close out a high-severity flaw codenamed  Reptar  that impacts its desktop, mobile, and server CPUs. Tracked as  CVE-2023-23583  (CVSS score: 8.8), the  issue  has the potential to "allow escalation of privilege and/or information disclosure and/or denial of service via local access." Successful exploitation of the vulnerability could also permit a bypass of the CPU's security boundaries, according to Google Cloud, which described it as an issue stemming from how redundant prefixes are interpreted by the processor. "The impact of this vulnerability is demonstrated when exploited by an attacker in a multi-tenant virtualized environment, as the exploit on a guest machine causes the host machine to crash resulting in a Denial of Service to other guest machines running on the same host," Google Cloud's Phil Venables  said . "Additionally, the vulnerability could potentially lead to information disclosure or privilege escala
SaaS Compliance through the NIST Cybersecurity Framework

SaaS Compliance through the NIST Cybersecurity Framework

Feb 20, 2024Cybersecurity Framework / SaaS Security
The US National Institute of Standards and Technology (NIST) cybersecurity framework is one of the world's most important guidelines for securing networks. It can be applied to any number of applications, including SaaS.  One of the challenges facing those tasked with securing SaaS applications is the different settings found in each application. It makes it difficult to develop a configuration policy that will apply to an HR app that manages employees, a marketing app that manages content, and an R&D app that manages software versions, all while aligning with NIST compliance standards.  However, there are several settings that can be applied to nearly every app in the SaaS stack. In this article, we'll explore some universal configurations, explain why they are important, and guide you in setting them in a way that improves your SaaS apps' security posture.  Start with Admins Role-based access control (RBAC) is a key to NIST adherence and should be applied to every SaaS a
Apache Tomcat Patches Important Security Vulnerabilities

Apache Tomcat Patches Important Security Vulnerabilities

Jul 24, 2018
The Apache Software Foundation (ASF) has released security updates to address several vulnerabilities in its Tomcat application server, one of which could allow a remote attacker to obtain sensitive information. Apache Tomcat is an open source web server and servlet system, which uses several Java EE specifications like Java Servlet, JavaServer Pages (JSP), Expression Language, and WebSocket, and provides a "pure Java" HTTP web server environment for Java concept to run in. Unlike Apache Struts2 vulnerabilities exploited to breach the systems of America credit reporting agency Equifax late last year, new Apache Tomcat vulnerabilities are less likely to be exploited in the wild. Apache Tomcat — Information Disclosure Vulnerability The more critical flaw ( CVE-2018-8037 ) of all in Apache Tomcat is an information disclosure vulnerability caused due to a bug in the tracking of connection closures which can lead to reuse of user sessions in a new connection.

Google Finds 7 Security Flaws in Widely Used Dnsmasq Network Software

Google Finds 7 Security Flaws in Widely Used Dnsmasq Network Software

Oct 03, 2017
Security researchers have discovered not one or two, but a total of seven security vulnerabilities in the popular open source Dnsmasq network services software, three of which could allow remote code execution on a vulnerable system and hijack it. Dnsmasq is a widely used lightweight network application tool designed to provide DNS (Domain Name System) forwarder, DHCP (Dynamic Host Configuration Protocol) server, router ads and network boot services for small networks. Dnsmasq comes pre-installed on various devices and operating systems, including Linux distributions such as Ubuntu and Debian, home routers, smartphones and Internet of Things (IoT) devices. A shodan scan for "Dnsmasq" reveals around 1.1 million instances worldwide. Recently, Google's security team reviewed Dnsmasq and discovered seven security issues, including DNS-related remote code execution, information disclosure, and denial-of-service (DoS) issues that can be triggered via DNS or DHCP. &q
This Hack Gives Linux Root Shell Just By Pressing 'ENTER' for 70 Seconds

This Hack Gives Linux Root Shell Just By Pressing 'ENTER' for 70 Seconds

Nov 16, 2016
A hacker with little more than a minute can bypass the authentication procedures on some Linux systems just by holding down the Enter key for around 70 seconds. The result? The act grants the hacker a shell with root privileges, which allows them to gain complete remote control over encrypted Linux machine. The security issue relies due to a vulnerability ( CVE-2016-4484 ) in the implementation of the Cryptsetup utility used for encrypting hard drives via Linux Unified Key Setup (LUKS), which is the standard implementation of disk encryption on a Linux-based operating system. The flaw actually is in the way the Cryptsetup utility handles password failures for the decryption process when a system boots up, which lets a user retry the password multiple times. What's even worse? Even if the user has tried up all 93 password attempts, the user is dropped to a shell (Busybox in Ubuntu) that has root privileges. In other words, if you enter a blank password 93 times – or s
Personal Data of 50 Million Turkish Citizens Leaked Online

Personal Data of 50 Million Turkish Citizens Leaked Online

Apr 05, 2016
Personal details of nearly 50 Million Turkish citizens, including the country's President Recep Tayyip Erdogan, have been compromised and posted online in a massive security breach. A database, which contains 49,611,709 records , appeared on the website of an Icelandic group on Monday, offering download links to anyone interested. If confirmed, the data breach would be one of the biggest public breaches of its kind, effectively putting two-thirds of the Nation's population at risk of identity theft and fraud. However, The Associated Press (AP) reported on Monday that it was able to partially verify the authenticity of 8 out of 10 non-public Turkish ID numbers against the names in the data leak. 50 Million Turkish Citizens' Personal Data leaked Online The leaked database (about 6.6 GB file) contains the following information: First and last names National identifier numbers (TC Kimlik No) Gender City of birth Date of birth Full address ID
