Cybersecurity researchers have disclosed a high-severity security flaw in the PostgreSQL open-source database system that could allow unprivileged users to alter environment variables, and potentially lead to code execution or information disclosure. The vulnerability, tracked as CVE-2024-10979 , carries a CVSS score of 8.8. Environment variables are user-defined values that can allow a program to dynamically fetch various kinds of information, such as access keys and software installation paths, during runtime without having to hard-code them. In certain operating systems, they are initialized during the startup phase. "Incorrect control of environment variables in PostgreSQL PL/Perl allows an unprivileged database user to change sensitive process environment variables (e.g., PATH )," PostgreSQL said in an advisory released Thursday. "That often suffices to enable arbitrary code execution, even if the attacker lacks a database server operating system user." ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added two security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerabilities are listed below - CVE-2012-4792 (CVSS score: 9.3) - Microsoft Internet Explorer Use-After-Free Vulnerability CVE-2024-39891 (CVSS score: 5.3) - Twilio Authy Information Disclosure Vulnerability CVE-2012-4792 is a decade-old use-after-free vulnerability in Internet Explorer that could allow a remote attacker to execute arbitrary code via a specially crafted site. It's currently not clear if the flaw has been subjected to renewed exploitation attempts, although it was abused as part of watering hole attacks targeting the Council on Foreign Relations (CFR) and Capstone Turbine Corporation websites back in December 2012. On the other hand, CVE-2024-39891 refers to an information disclosure bug in an unauthenticated endpoint that could be exploited to "accept ...

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 E...

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 escal...

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. The vu...

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. ...

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 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...
